The trio races to catch Flynn in 1972 before he can steal the mysterious missing minutes of the Watergate tape, but personal secrets threaten to tear the team apart.

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.

While Wyatt sneaks away from the bunker to face an unbelievable truth, Lucy, Rufus and their former enemy-turned- teammate, Garcia Flynn, chase the Mothership to the Salem Witch Trials. There they must prevent the execution of a headstrong young woman who, it turns out, is mother to one of the most consequential Americans of all time – the yet to be born Benjamin Franklin. When Lucy is accused of being a witch, the team rallies together not only to save Abiah and Lucy, but all the accused women.
