The cops have no interest in any of the suspects in the line up. Laura Mansfield (Joyce MacKenzie) does. She's has a hunch one of them is the person she saw running away after her father was gunned down. The law turns the man free. Laura, a college student with no training as a detective, turns herself loose on the case. Feigning romantic interest, she becomes part of the suspect's world, putting herself on a twisted trail of hit men, nightclubs, blackmail and false identities that leads to Destination Murder. An assassin who can only do his vile deeds while Moonlight Sonata plays is one of the lapel-grabbing flourishes of this noir programmer from prolific 'Killer B' director Edward L. Cahn (Our Gang shorts, It! The Terror from Beyond Space).
