Escondido, California, 1994. It's the end of summer and Gene is preparing for his high school drama friends' final murder mystery slumber party. The theatrical hostess, Rose, will fly off to start college the next morning, followed by earnest Claire, magnetic Oscar, and sarcastic Ally. Yet Gene has bigger problems than being left behind by his best friends: he wants to come out of the closet - but is terrified of what they might think. Once Gene arrives to the party, his burdensome secret isn't the night's only obstacle. An unexpected visit by JD, a judgmental rebel, sews the seeds for discord and makes the sheltered Christian teens question their readiness for the "real world" to come. Will the tested friendships survive the night - and the enormous life changes that loom?
