After a mysterious drug called NZT gives him the ability to use 100% of his brain, Brian Finch uses it to help his sick father, but he also finds himself a suspect in the murder of the man who gave him the drug, and to clear his name he must find the real perpetrator. Written by Preston Hahn

Brian hoped to become a dashing field agent, but Rebecca's superior mistrusts him and assigns him a desk job as analyst. Brian is relieved when suggested he can confide in his father using lawyer-client confidentiality, but notices the nurse is on the senator's pay-role. As the FBI investigates the apparent accidental death of an investigative reporter, Brian proves able to work out it's a crime to cover up a more elaborate plot, even if that requires throwing off his office guards and roaming about the city, and again despite a threat that would get him fired. Written by KGF Vissers

Finally promoted to field agent, Brian does a great job working out in collaboration with the NYPD how the murder of one of their cops concerns the hunt for Mexican drug baron Marco Ramos, and how to prevent the surprising culprits escaping extradition.

An elderly scientist Brian befriended on-line appears at the bureau asking for his help. His woes soon worsen when evidence points to him murdering a former colleague who made a personal fortune from their work.

When a hunt for a meth lab becomes a hunt for terrorists targeting New York City with a dirty bomb, Brian collides and bonds with a concerned lad who doesn't realize his older brother's been recruited.

Memory loss, extreme paranoia, rapid aging, encroaching psychosis, as well as aphasia and metamorphopsia (distorted speech and vision). With the first inoculation wearing off, these become Brian's experiences as, privately hurtling towards pain and madness, he helps Rebecca look into her father's NZT-related past (having shared the stolen files with her). With Rebecca unexpectedly pulled away into an FBI war game, the side-effects worsen, with the next inoculation withheld till Brian carries out a new assignment: discredit Rebecca.

When Brian calls in sick for a day off from the FBI, the CIA abducts him from home to borrow his NZT-enhanced capabilities for a black ops mission. As the operation becomes increasingly dangerous, Brian finds himself without FBI support in a situation that's spiraling out of control.

Naz' attempt to ferret out the person who signed off on using Brian in the illegal C.I.A. black ops mission ends with her arrest for secretly funding terrorists. As Boyle feigns to conspire with interim leader ADIC Grady Johnson to continue the hunt, Brian and Rebecca (in hiding) resolve to get Naz off the hook but find she's technically guilty, paying a shady intermediary for the safe return of her teen daughter Ava's kidnapped cousin Mitra, taken by South China Sea pirates. Tapping into his secret pill stash, Brian learns every language in the region to identify, contact, and deal with the current kidnappers (pirates who've pirated other pirates for the cousin).

Under NZT, Brian offers to capture the FBI's Ten Most Wanted criminals in two weeks in exchange for Naz giving him his own personal work headquarters at the agency. Under her reluctant agreement, Brian assigns various agents tasks while willing himself into developing a new felon-hunting technique through NZT - synesthesia, the ability to see fragrances and odors - but a snag develops when he finds one fugitive unlikely of his crime. To clear him expediently would take dosing him with NZT, but could the FBI ever agree to that? Meanwhile, the secretive nature of Brian's new life working for the Bureau creates a rift between him and his father. Written by Anonymous/edited by statmanjeff

Brian's bodyguards go to the NZT dispensary to pick up his daily dose and find a break in, with the thief still there. A shootout breaks out, but the perp escapes with his haul. With Brian's help they figure out where they can find the drugs, but a large amount of the NZT disappear between the drug bust and the FBI. Who took it and what will they do with it?

A remarkable assassination attempt on Sen. Morra sends Sands to summon the FBI directly, but his primary mission is to alert Brian of the need to keep the investigation from rightfully naming Piper Baird as the assassin, as her ties will ultimately reveal Morra's secret connection to NZT. Piper, on the other hand, aims to draw fellow NZT user Brian to her cause of ending Sen. Morra before he causes further murders en route to his bid for the presidency, leaving Brian feeling caught in the middle over who to believe and trust. Written by statmanjeff

SPOILER: Rebecca and Brian have an unconventional interview with a robotic version of a murder victim that was created before her demise - ELO.2.0, aka Eloise.

After a list with the real identities of undercover bureau operatives leaks, Brian develops a personal connection with FBI Agent Lucy Church (Christina Vidal), a tenacious rule-breaker, when he helps her finish a field case before she's exposed.

Sands, with a large shard of glass protruding from his leg, arrives at Brian's house while Brian's sister Rachel visits.

Meanwhile, reluctant birthday girl Rebecca and the FBI investigate a chance kidnapping, which turns into anything but. Written by Blake Russell/edited by statmanjeff

When Rebecca finally confronts Brian about not answering his phone, she is interrupted by a city power blackout. Investigating the premises of a power plant exposes them to a substance of unknown origin that may come from outer space. As a result, they are put under quarantine and must work the case from isolation. They also need to solve their own issues. In the meantime, Rachel discovers Brian's stash of NZT pills and starts questioning her brother's association with the FBI. Written by Andreea D/edited by statmanjeff

Feeling alternately cornered, controlled and abandoned on all fronts, Brian flees to Russia where he hopes to find Piper to help him break free of his dependence on Sen. Morra's immunization shots. Their bond deepens as they plan how to steal the last ingredient needed to recreate the booster enzyme, to the point where Brian considers forming a more permanent relationship with Piper and leaving his NZT-enhanced life behind. Meanwhile, as the fruitless search for Brian continues in the States, Rebecca learns a disturbing fact about him. Written by statmanjeff

Rebecca confronts Brian at gunpoint about his connections to Senator Morra and Jarrod Sands. To perceive the truth, and knowing of the adverse aftereffects to come, she takes NZT and learns Brian's complete story. Now on NZT together, they tackle the problem of bringing down Sands through Huston's burn book, which unexpectedly reconnects Rebecca to her late father while it leads the pair to try breaking through the barrier of a coma. Meanwhile, gratitude interferes with Sands' ability to be the ruthless leader of his new coalition. Written by statmanjeff

With full disclosure ousting him from the FBI (and without NZT to aid him), Brian fruitlessly searches alone for the kidnapped Piper, but a sudden proliferation of NZT on the streets presents a mixed blessing. It keeps authorities further from aiding in Piper's search but avails Brian the smart drug. Now he can turn to Apocryphon, a word he wrote down weeks ago while under the influence, which crops up only now in the NZT epidemic. Meanwhile, as Sands sits in jail, his Legion of Whom (as Brian puts it) puts into play their first nefarious plans. Written by statmanjeff

As his inoculation wears off, and with no further boosters forthcoming from the missing Senator Morra, Brian endures the nightmarish side effects of NZT usage in order to find Sands, his Legion of Whom team, and Piper (for whom he's prepared to make the ultimate sacrifice). Deducing that the Legion needs lots of immediate cash, Brian and the bureau track down Clay Meeks and try to determine how the Legion's objective can be reached through international politics, global warming and murder. All the while, as more people die, Brian's condition worsens. Written by statmanjeff
