Wyatt and Rufus steal the Lifeboat to travel to Toledo, Ohio, on March 19, 1983, to circumvent the one-night stand between the parents of Jessica's killer: a bartender and a stewardess. After several unsuccessful attempts, Wyatt chases the bartender outside in the midst of a hurricane. The bartender trips over debris resulting in a fatal fall. Meanwhile, Emma tells Flynn and Anthony about Rittenhouse's real intentions for the time machines. Flynn wants to continue eradicating Rittenhouse, but Anthony thinks they should destroy both machines. Anthony confides in Lucy his plans for sabotage.
Lucy tells this information to Agent Christopher and they agree to keep it to themselves, and learns of Mason's dealings with her biological father, Benjamin Cahill. When Wyatt and Rufus return to the present, they discover Jessica is still missing but the other two women were saved, but Wyatt is taken into custody. There is a big explosion where the Mothership was parked, but the team notice a lack of debris from the machine and Anthony's body in the rubble with close-range gunshot wounds. They realize that Flynn discovered what Anthony was doing and escaped in the Mothership. Lucy confronts Cahill about Rittenhouse.
