This muddled murder mystery-comedy was based on the Max Marcin stage play The Night Cap. Bank president Robert Andrews (James Kirkwood) has loaned someone money out of the bank funds and he wants to distract the bank examiner from examining the books and discovering the shortage. So he invites him, and the directors, over to his house. All sorts of intrigue happens at the gathering -- Andrews argues with Jerry Hammond (Tom Ricketts), who is in love with his ward, Anne Maynard (Madge Bellamy). Lester Knoles (Arthur Stuart Hull), meanwhile, is jealous of Andrews' friendship with his wife (Rosemary Theby). In addition, we discover that Andrews has a life insurance policy that will cover the shortage should he die. Not too surprisingly, after some strange goings-on, Andrews is found dead in Mrs. Knoles' room. The police investigate and everybody seems to have a motive to kill Andrews. A lot of confusion ensues, until it is discovered that Andrews isn't really dead after all, and the man who he loaned the money shows up and straightens things out. It's also revealed that the bank examiner has given up his job in favor of selling real estate.
