"Limitless" movie star Bradley Cooper (pictured) will reprise his role as Ed Morra in the CBS spinoff series of the same name in episode 6, titled "Side Effects May Include..." CBS

The good guys seem to be losing on the hit CBS movie spinoff series “Limitless.” Although the battle lines are forever murky in a show with so many twists and turns, it seems like Brian Finch (Jake McDorman) has stacked the deck against himself going into episode 6.

During the latest installment of “Limitless,” it was made clear to Finch that his cooperation with Senator Ed Morra (Bradley Cooper) was a requirement for Morra to inoculate him with his super secret vaccine that stops the side effects of the superdrug NZT. Without it, Finch’s constant recreational use of the drug while working for the FBI would have likely killed him by now. Unfortunately, the vaccine doesn’t last forever and Finch seems like he’ll be in need of another inoculation in episode 6, titled “Side Effects May Include…”

“Brian’s physical and mental health begin to deteriorate again,” reads the episode’s TV Guide synopsis. “But Edward Morra is demanding a high price in exchange for another inoculation.”

It looks like Finch’s luck taking NZT every day will finally run out. As seen in the first episode of the series, the side effects of NZT withdrawal are a long and slow process that ultimately leads to death. This means that there are precious few lengths that someone in need like Finch will go to in order to get the shot he needs. However, that doesn’t mean Morra isn’t still capable of exceeding those lengths.

In a TV spot for the upcoming episode, which teases yet another appearance by "Limitless" film star Bradley Cooper, his associate lays out the deal to get Morra more of the NZT vaccine. During this week’s episode, Finch revealed to the mysterious Mr. Sands (Colin Salmon) that he's looking into the death of Rebecca Harris' (Jennifer Carpenter) father. This proves irksome to Sands, who wants Brian to simply do his job and not take on side projects, especially when those side projects flirt with the FBI learning about Morra’s connection to NZT.

As a result, in a preview clip for the upcoming episode, Mr. Sands tells Finch that the only way he’s getting the medicine he needs is if he removes Rebecca from the equation. Obviously, the show’s principal character has no intention of killing his friend, so Sands appears to allow Brian to die the slow and painful death that his employer promised him in episode 2.

Tune in to “Limitless” on CBS next Tuesday at 10 p.m. to find out how it will all play out for Brian and Rebecca.
