Limitless : Season 1

Brian Finch's life takes an extraordinary turn when he uses a mysterious drug, NZT, that allows him to access his full brain capacity. However, when an NZT-related murder lands Brian on the FBI's radar, he uses the drug in an attempt to stay ahead of the authorities long enough to clear his name.

Brian risks his new FBI job when he disobeys orders to stay out of the investigation into a renowned journalist’s murder.

When Agent Casey Rooks and his SWAT team skim 80 NZT pills for themselves from the recovery of stolen inventory, it starts an internal investigation that is viewed through the shifting perspectives of Brian’s immediate circle at the FBI.

When an assassin makes an attempt on Senator Edward Morra's life, Brian is ordered to sabotage the FBI's investigation into it in order to prevent exposing the Senator's connection to NZT. As Brian and Morra's fates become further intertwined, Brian is faced with how far he's willing to go to protect the politician.

Brian embarks on his first FBI field assignment when he travels to Quantico to lend his skills to the bureau unit that catches serial killers. However, the trip takes a negative turn when Brian realizes the man he's working with may have put away an innocent person in the career-making case that made him a renowned profiler. Also, Brian tries to stay one step ahead of Rebecca as she comes closer to discovering Senator Morra's connection to NZT.

When Sands, Senator Morra’s deadly representative, enlists Brian’s help to eliminate an immediate threat he needs to keep secret from the politician, Brian learns Sands’ dangerous and shocking past. Also, Brian’s sister, Rachel, scrambles to cover up his abrupt side mission with Sands when the FBI can’t reach him regarding a new case.

Brian and Rebecca are placed under quarantine by the CDC after being exposed to an unknown substance after investigating a citywide blackout. Also, trust issues arise after Rebecca catches Brian using his secret stash of NZT.

Brian’s double life unravels when Senator Morra makes contact just as Brian’s placed under 24-hour surveillance by the FBI following his rogue trip to Russia. Also, Mike and Ike tell an already suspicious Rebecca about Brian’s off-book interaction with Morra’s henchman, Sands.
