Time-traveling rogue, Rip Hunter, has to recruit a rag-tag team of heroes and villains to help prevent an apocalypse that could impact not only Earth, but all of time.
The team meet Vandal Savage, who senses the presence of Hawkman and Hawkgirl. A fight follows in which Ray loses a piece of his costume that threatens to change the future. Then the team plan to correct that.
In an effort to weaken Savage by going after his financial assets, Rip and Sara infiltrate his bank. Meanwhile, Snart and Rory take the jump ship back to Central City for a job.
After some of the Legends are captured and thrown into a Russian gulag during the height of the Cold War of 1986, Snart leads the team in an elaborate Prison Break 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.
When there's no trace of Savage, Rip spends time dwelling on the past and Rory continues to be a liability to the team. The crew receive a distress call from another Time Master and seek it out, only to find that the ship was commandeered by time pirates. Snart has an important decision to make.
The Legends travel back to the Old Wild West and gain the aid of a true legend - a morally ambiguous gunslinger with a penchant for danger named Jonah Hex.
Rip takes the team to London in the year 2166, three days before his family is killed. He believes this to be their final opportunity to take out Savage who is, unfortunately, at the height of his power. However, the team discovers two key elements to defeating him - Savage's daughter and the means to kill Savage once and for all.
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.
After the numerous sacrifices the team has made since the beginning of this ride, Rip decides that it's time they each decide their own destiny and returns them to Central City a few months after they first left. Returned to their normal lives, each team member must individually decide if they are willing to sacrifice everything in order to save the world. Meanwhile, Sara visits with her father who delivers some heartbreaking news about her sister.
