Rue's just finished high school and now he's stuck in a rut-and in the closet-with no social life and a home life he'd rather avoid. He's engaging in one of his favourite hobbies, stranding himself on the beach and waiting for the tide to free him, when he spots someone less intentionally stuck in the same predicament.

He thinks the apartment next to theirs is empty, until one day he hears a sound from next door...
