Dr. Steven Bishop is taken to the hideout of Frank Dillon and his gang to treat the wounded Joe Madison. Joe's nurse sister Nora Madison is also taken. Dillon tells Bishop that if Joe dies, he will be killed, but Bishop knows he will be either way. Joe dies, but Nora and Steve conceal it from Dillon and send a plea for help in a prescription that Bishop writes in Latin.
When one of their number ("Joe") is shot during a robbery, the gangsters responsible try to seek the help of a doctor. The first they find claims that he needs hospital treatment and that's soon the end of him. They move on to another, "Bishop" (Regis Toomey), and lure him to their hideout where he discovers the sister of the wounded man "Nora" (Adele Longmire) who also happens to be a nurse. They are given a very thinly veiled ultimatum - save his life or lose their own. Both reckon they are doomed either way, so have to find a way of getting a message out to the pursuing police before they are toast. Just to add a little spice to the proceedings, "Nora" also happens to be the moll of boss "Dillon" (the not very menacing Howard Da Silva) so some conflict looms? Though it is quite watchable, it hasn't really an original bone in it's body and appears to be supplemented with some archive footage from similar crimes-noir. The denouement is just a little different but for the most part it's all join-the-dots stuff that you've seen before with a cast and writing that's probably just as adequate.
