A husband is on trial for the attempted murder of his wife, in what is seemingly an open/shut case for the ambitious district attorney trying to put him away. However, there are surprises for both around every corner, and, as a suspenseful game of cat-and-mouse is played out, each must manipulate and outwit the other.

Madeline is married to Ernest, who was once arch-rival Helen’s fiance. After recovering from a mental breakdown, Helen vows to kill Madeline and steal back Ernest. Unfortunately for everyone, the introduction of a magic potion causes things to be a great deal more complicated than a mere murder plot.
