Last time on "Limitless" episode 10 "Arm-ageddon", we saw how Brian finally confessed to his dad Dennis about the NZT drug and what he has been up to in the past few weeks. But, this did not work in Brian's favour as Dennis promptly tried to figure out how to get Brian out of the FBI and away from NZT. The episode also showed Dennis gearing up for a legal battle against Brian's bosses, while he was still busy catching a murderer. Meanwhile, Dennis has somewhere exposed Brian to danger that Morra will find out.

"Arm-ageddon" also delved deeper into Boyle's backstory, introducing the viewers to one of his old army ranger buddies Aaron Shaw. We saw how Brian is asked by Agent Boyle to help with his ranger friend whose wife was killed by his brain-controlled prosthetic.

In this week's episode 11, Agent Casey Rooks and his team break into the dispensary and steal around 80 NZT pills for themselves, but this triggers an internal investigation called by Head of Operations, Naz. The promo of "This is Your Brian on Drugs" also shows Brian's struggle in keeping everyone alive, especially after he told his dad Dennis Finch (Ron Rikfin) the truth about NZT. It would be interesting to watch what will happen once Senator Morra comes to know that someone else other than Brian knows about NZT. Until episode 10, the politician was still unaware that Brian has confessed to his dad about the drug.

Plot synopsis of "This is Your Brian on Drugs" reads: "When Agent Casey Rooks (Desmond Harrington) 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."

"Limitless" Season 1 Episode 11, titled " This is Your Brian on Drugs", will be aired on CBS at 10 pm on 15 December.
