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.

Summoned to an emergency meeting, the siblings hatch very different plans for how to spend their last six days on Earth. Lila confronts her mother.

Allison gives Ray a peek at her powers, Dave visits Klaus's compound, the Handler offers Five a deal, and the siblings meet their father for dinner.

After Five travels to 1982 to carry out his new mission, the siblings face a flurry of difficult decisions. Carl issues a warning to Vanya.

A desperate Five concocts a risky plan to intercept another version of himself. The FBI tortures Vanya. Diego discovers what causes the apocalypse.

As the Fives plot against each other, one of the siblings makes a big sacrifice to help Vanya, and Lila learns the truth about her parents.

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.
