DC’s Legends of Tomorrow airs 8 p.m. Thursdays on The CW. Here’s the official synopsis of “Fail-Safe”:
THE TEAM ORCHESTRATES A PRISON BREAK – After some of the Legends are captured and thrown into a Russian gulag during the height of the Cold War of 1986, Snart (Wentworth Miller) leads the team in an elaborate escape plan to free their comrades. However, Rip (Arthur Darvill) gives Sara (Caity Lotz) a secret side mission that could prove not only to be a liability, but fatal to the team. Dermott Downs directed the episode written by Beth Schwartz & Grainne Godfree (#105).
