The creative team responsible for a recent Broadway flop (in which three chorus girls were murdered by the mysterious “Stage Door Slasher") assemble for a backer’s audition of their new show at the Westchester estate of a wealthy angel. As the composer, lyricist, actors, and director prepare their performance, and a blizzard cuts off any possible retreat, bodies start to drop in plain sight, knives spring out of nowhere, masked figures drag their victims behind swiveling bookcases, and accusing fingers point in all directions.
