With the identity of the Beast finally revealed, Scott and his friends are in a race against time to stop The Dread doctors from implementing their final plan.

Upon learning that Lydia is in danger, Stiles makes a plan to break her out of Eichen House; Theo has his own plans.

While trapped in Eichen House with Theo and the Chimera pack, Scott tries to rescue Lydia before time runs out.

As Scott tries to put his pack back together, Malia and her new ally set out to rescue Deaton from The Desert Wolf.

Even without the support of his pack, Scott considers what the Dread Doctors’ success means for Beacon Hills.
