Jennifer Smith heads a "Consumer Reports"-type company and her reputation for honesty is her greatest asset. While out boating one day she encounters a secret prototype submarine piloted by Bill Craig. Trying to explain her absence after her boat sinks becomes very difficult as Bill and his cohorts attempt to discredit her story.
