Following the car accident that ended his football career and left his body scarred, 22-year-old Luke Griffin joins the cast of “Endeavor,” a new competition-based reality show that pits the tabloids’ darlings against one another in tasks of endurance and problem solving. But Luke has aspirations far bigger than the show's million-dollar prize, and soon a series of betrayals leads to irreversible tragedy. Ten years later, Luke is a father of two and the stay-at-home husband to America’s only openly gay senator. When his husband's serial cheating is exposed, Luke impulsively joins the cast of the latest season of “Endeavor” in a desperate bid to earn some fast cash. Back on set, he is confronted with everything he tried to leave in the past: bitter rivalries, shattered friendships and crushing guilt, all of which threaten to tear down the walls he’s spent a decade building.
