While Wyatt (Matt Lanter) sneaks away from the bunker to face an unbelievable truth, Lucy (Abigail Spencer), Rufus (Malcolm Barrett) and their former enemy-turned- teammate, Garcia Flynn (Goran Visnjic), 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 (guest star Sofia Vassilieva) and Lucy (Abigail Spencer), but all the accused women.
