After dropping his siblings into an alley in Dallas — in different years — Five scrambles to track them all down and stop a new doomsday threat.

An incident at the bar leads Luther to Vanya. Five finds an unsettling surprise in the film Hazel left behind. The cops come after Allison's husband.

As the sit-in approaches, Allison reconnects with Klaus, the Swedes chase Vanya into a cornfield, and Luther makes a distressing discovery.

While Allison searches frantically for Ray, Vanya contends with a crisis at the farm, and Five, Diego, and Lila crash a party at the Mexican Consulate.

Reeling from the events at Dealey Plaza, the siblings head to the farm to help save Harlan — only to find themselves drawn into a deadly showdown.
