Fail-Safe

"Fail-Safe" is the fifth episode of the first season of DC's Legends of Tomorrow, and the fifth episode overall. It aired on February 18, 2016.

Synopsis
After some of the Legends are captured and thrown into a Russian gulag during the height of the Cold War in 1986, Snart leads the team in an elaborate escape plan to free their comrades. However, Rip gives Sara a secret side mission that could prove not only to be a liability, but fatal to the team.

Trivia

 * While discussing the rescue mission to retrieve Martin Stein, Mick Rory and Ray Palmer from the Russian gulag, Leonard Snart mentions that "this isn't my first prison break". This is possibly a reference to Wentworth Miller's former role as fugitive Michael Scofield in the TV series Prison Break, notorious for his Fox River and Sona prison escapes.
 * Rory also refers to Ray as "pretty" while being escorted to their cell, a common nickname that character Theodore Bagwell would call Michael Scofield by on the television series Prison Break.
 * The hooded archer shown at the end is intended to be Connor Hawke, who is Oliver's son in the comics.
 * When Jefferson Jackson runs across the field, he says "Barry Allen who?". This is a reference to "The Flash".
