As an experiment to find out if spouses are truly capable of murder if given the chance, psychology professor James Parkerson (Barry Nelson) places a newspaper ad offering the "ultimate solution" for domestic discord. When the authorities protest, Parkerson assures them that his experiment is strictly theoretical, and that he intends to do no harm. But circumstances change considerably when a prospective client named Johnson (Richard Dawson) asks Parkerson's help in devising a method to kill the husband of Johnson's girlfriend -- whereupon the professor realizes that he is being asked to plan his own murder.
