The creative team behind a recent Broadway flop (where three chorus girls were killed by the “Stage Door Slasher”) assembles for a backer’s audition at a wealthy angel's estate. The mansion, full of sliding panels and secret passages, becomes the backdrop for comic mayhem when the Slasher strikes again. Amidst a blizzard, bodies drop, knives appear, and accusations fly. With help from a bumbling police inspector, the mystery is solved just in time, providing the audience with plenty of laughs.
