A woman enters a bar asking for whatever will give her courage, or make her forget. When she is awakened on the morning after the night before, it appears she may have found a glass of exactly what she wanted, for she is arrested on suspicion of murder. The death of a rival in agricultural research, who she claims stole an important biological innovation she invented, is being blamed on her. With the help of a sympathetic policeman, they attempt to solve the mystery together.
