Radio singing star, Eve Porter, wants a vacation during her show's summer hiatus, but her manager and press have booked her for additional work. She refuses and goes to Las Vegas. When she finds them there hunting her down, she manages to escape them by hiding in the car of a newspaper reporter. She comes out of hiding while he is driving, but everything she says is misconstrued, making him believe that she is a recently-escaped convict, "The Singing Widow". He plans to use this as a story to get back into the good graces of his editor. Through some comic mishaps, he learns who she really is. He then decides to take her back to Hollywood to collect the reward for her return. But now love has entered the mix, and must be resolved with his job and her engagement to another.

During World War II, all the studios put out "all-star" vehicles which featured virtually every star on the lot--often playing themselves--in musical numbers and comedy skits, and were meant as morale-boosters to both the troops overseas and the civilians at home. This was Universal Pictures' effort. It features everyone from Donald O'Connor to the Andrews Sisters to Orson Welles to W.C. Fields to George Raft to Marlene Dietrich, and dozens of other Universal players.
