A beautiful young MIT graduate (Danica McKellar) witnesses a sailor being strangled. Local police doubt her story, but McGee asserts that her account warrants further investigation. When a sailor's body is found at another location, the story gains ground. The witness also captivates McGee who, after a sudden twist in the investigation, ends up unknowingly holding the key to solving the case.
