Back in 1969, the team goes undercover at NASA to stop Flynn from sabotaging the moon landing and killing the crew of Apollo 11.

On the run with the bank-robbing Barrow gang, the team needs to gain the trust of ill-fated lovers Bonnie and Clyde in order to find out Flynn's target in the Depression-era South. While Agent Christopher tracks down a lead in present day, Lucy, Rufus, and Wyatt risk getting caught in the crossfire, suspecting that whatever Flynn's after may be a key piece of the whole puzzle.

A stunning turn during the American Revolution prompts Lucy, Wyatt, and Rufus to question whether they've been fighting on the wrong side this whole time. While Agent Christopher prepares for the worst back in present day, the team encounters the Father of the Country, makes a dubious pact, and confronts the possibility they may not be a trio for long.

Lucy's situation grows desperate after she's taken captive by Flynn and brought to the 1893 Chicago World's Fair. In their dogged pursuit of Lucy, Wyatt and Rufus fall into a sinister trap.

Flynn teams up with legendary outlaw, Jesse James. Together they cut a bloody swath across the American frontier. Hot on Flynn's trail, Lucy, Wyatt, and Rufus enlist the help of an iconic Marshal to help bring the fugitives to justice.

Wyatt convinces Rufus to steal the Lifeboat for an unauthorized mission to prevent Wyatt's wife's killer from ever being born. Lucy must cover for them in the present, as Agent Christopher discovers the ship is missing and Anthony Bruhl makes an alarming confession.

As Lucy grapples with her newfound identity, Flynn disappears to 1927 France on the day that Charles Lindbergh completes his transatlantic flight. Now, Rufus, Lucy and their new soldier scramble through the City of Lights and team with young reporter, Ernest Hemingway, to keep history intact.

Flynn travels to 1931 Chicago to partner with gangster Al Capone. Lucy, Wyatt and Rufus, meanwhile, team up with the only man who can bring Capone down: federal law-enforcement agent Eliot Ness.

With one of our heroes' lives on the line, the team chases Flynn to 1954 through the paranoid corridors of Joe McCarthy's Washington D.C., en route to a secret, once-a-generation meeting of Rittenhouse leaders. While there, Lucy must wager the ultimate sacrifice to save history as we know it.
