Nuclear scientists mysteriously disappear when Vandal Savage retreats behind the Iron Curtain in the early 1980s. The team follows Vandal's trail in an effort to find his next target, while Ray bonds with a beautiful Soviet scientist. Stein pushes Jax to be better, which frustrates Jax and ultimately threatens the Firestorm matrix. Rip asks Sara to train Kendra.

The team is targeted by The Pilgrim, a deadly assassin who wants to erase the Legends from the timeline by killing their younger, non-superhero selves. As a protective countermeasure, Rip decides Sara, Snart, Rory, Professor Stein and Jax need to kidnap their past selves first before The Pilgrim gets to them. Coming face-to-face with the younger versions of themselves proves to be both a physical and emotional challenge for certain members of the team who would rather forget their past. Rip tells them he has a refuge for their precious cargo – an orphanage that raises future Time Masters and where he himself grew up.

After numerous attempts in many different time periods, the team has successfully captured Vandal Savage. However, Savage tells Kendra that he can reunite her with Carter so she struggles with whether she should kill him. Rip decides they will deliver Savage to the Time Masters which doesn’t sit well with Snart and Rory. The duo decides it may be time to jump ship and return to their old life. Meanwhile, Savage taunts Ray about his place in Kendra’s life.

Being in the vicinity of the Time Masters leaves Rip and Rory incredibly disturbed for very different reasons. Meanwhile, Sara takes over the Waverider, Kendra is reunited with Carter and Snart decides he might be a hero after all.
