Jailbreak is a formula Warners "B" with all the attendant stereotypes. Dick Purcell plays a convict accused of murdering a fellow prisoner. Craig Reynolds, a temporarily incarcerated reporter, sets about to prove Purcell's innocence. June Travis is the "girl on the outside," awaiting the release of Reynolds and acting as his conduit to the "free" world. To no one's surprise, prison-flick veteran Barton MacLaine is also in the picture--but to everyone's surprise, he's one of the good guys. Jailbreak was remade in 1942 as Murder in the Big House, which represented one of the earliest screen appearances of Van Johnson.
