It's Christmas Eve when hapless musician Adam Banks stands on the bridge over the river that cleaves the isolated village of Burton. A storm is rolling into the narrow mountain pass. He thinks of turning back. Instead, he resolves to fulfill his obligation to perform the guest spot at The Cabin Sessions. Fear stirs when he opens the door on The Cabin's incense-choked air. Local plumber Philip Stone is already there, brooding. Meanwhile, Philip's sister Eva prepares to take a bath. Memories begin to surface concerning one fateful day by the river, and the innocence of her beloved brother.
