Ernie's Uncle Gabriel has just died but to claim his inheritance he must spend the night in the ancestral family home with the rest of his rather eccentric relatives. Ernie's imagination has been affected by his constant immersion in cheap horror novels, but his wildest fears turn out to be justified when the guests begin to drop dead.
