Jacob Zachar gets sandwiched between on-screen sister Spencer Grammer and Scott Michael Foster in this new promo pic from GRΣΣK.

Picking up where it left off, with the events from last season’s “End of the World” party dramatically revealing themselves in the first episode, “The Day After.”

After learning of Max’s departure, Cappie (Foster) wonders if he made the right decision by telling Casey he wasn’t interested in giving their relationship another chance, while Casey (Grammer) struggles with the aftermath of Cappie’s unexpected rejection; Rebecca’s (Dilshad Vadsaria) late night kiss with a mystery man can’t stay a secret for too long; and Rusty (Zachar) risks failing in o-chem and losing his honor status, while roommate Dale (Clark Duke) faces a huge moral dilemma.

Watch out for HSM‘s Olesya Rulin — she’ll have a recurring role as Abby.

“The Day After” premieres Monday, August 31 @ 9PM ET/PT on ABC Family.
