In the new episode of "Limitless," Naz is suspected of funding terrorism and while Brian and Rebecca try to find a way to help her clear her name, the two will discover her biggest secret that she's been hiding from the FBI for a long time.

CBS's TV adaptation of Bradley Cooper's 2011 film is approaching its eight episode titled, "When Pirates Pirate Pirates," where Brian and Rebecca team up to help Naz with her situation. The FBI special agent is detained on suspicion of treason and the duo take it upon themselves to help her. However, Brian and Rebecca will find out about Naz's daughter, whom she'd been hiding for a long time, in their effort to clear the agent's name, The Futon Critic wrote.

In the last episode titled, "Brian Finch's Black Op," Brian was "kidnapped" by his colleague from Virginia and used him in tracking down a terrorist, io9 reported. Viewers also saw Jake McDorman talked to himself once again but this time, with the good and evil versions of Brian. Jennifer Carpenter's Rebecca also appeared in his conversation, which confirmed that his internal struggle involves other people as well.

Episode 7 also revealed that someone besides Brian is also taking NZT, which sparks speculation that one of the main characters could also take the drug in the future episodes.

But what surprised the fans of "Limitless" is its Ferris Bueller's Day Off homage early in its first season. TV.com commended the series paying respect to the film without "diving too far into shot-for-shot remake territory," which showed the creative thinking among the writers.  

FBI special agent Naz's biggest family secret is about to be revealed in the upcoming episode of "Limitless" titled, "When Pirates Pirate Pirates." Brian and Rebecca will help Naz clear her name after she was suspected to be funding  terrorism.

"Limitless" airs Tuesdays on CBS.
