Originally bound for Harvard, Jeff joins the family detective business to save his mother and sister from eviction. He learns the ropes quickly when a gangster hires him to find out if his bombshell fiancee is two-timing him. Shadowing her every movement - and eyeing her every curve - Jeff lands in real hot water, not to mention a hot shower, when thugs kidnap her lover and try to get him. Now they're both on the run - from the mob, from the police (who might be working with the mob), and from his mother (who might pose the biggest danger of them all)!
Unfortunately the movie The Gumshoe Kid is not yet available on HBO Max.
