Fugitive in Trieste.

An Italian Air Force officer is pursued and captured by the Allied police and is charged with the bombing of a hospital ship. Through the efforts of his sweetheart, a witness is found who proves the bombing was not intentional but the result of being hit by enemy fire. A four-way romantic involvement is also part of the mix that includes an Allied officer and Viennse beauty Lida. The latter was once in love with the accused and has a child by him.
