Pretty Little Liars: Summer School, Episode 3

The girls eagerly await a verdict in A's trial until a failed exam condemns them to a fate worse than death: summer school. Mouse investigates a spooky online legend and Kelly becomes an active member of a cult-like youth group.

Haunted by increasingly disturbing hallucinations, Imogen attempts to forge a new identity outside of Millwood. As summer kicks off, Noa reconnects with an old friend and Tabby meets her movie-buff match.

When their identities are revealed online, the PLLs scramble to figure out who is behind a series of anonymous calls - and keep Mouse's surprise birthday party under wraps. Faran finally spills her secret.

Still shaken from her encounter with Bloody Rose, Mouse searches for the real Rose Waters. Imogen keeps tabs on Dr Sullivan, Tabby works on a new short and Faran's strength is put to the ultimate test.

After a disturbing discovery, the PLLs start to question Dr Sullivan's intentions. While Tabby and Christian get ready to host a movie marathon, Faran loses faith in Henry, and a torn Noa must choose between Jen and Shawn.

After discovering that Kelly's church is using her former home for their disturbing 'Hell House,' Imogen springs into action. The PLLs' plan to freak out the faithful takes a frightening turn.
