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 hitmen, 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).

Producer-director Edward L. Cahn's Prominent Pictures produced this low-budget thriller-noir which was then sold outright to RKO. Joyce MacKenzie stars as Laura Mansfield whose father (Franklyn Farnum) is killed in cold blood by smalltime hoodlum turned messenger boy Jackie Wales (Stanley Clements). But the latter has a seemingly ironclad alibi and Laura goes undercover as a nightclub cigarette girl to trap him. Unbeknownst to the heroine, however, Wales is blackmailing Armitage (Albert Dekker), the ruthless nightclub operator who had hired him to murder Mansfield in the first place. But is Armitage the real "Mr. Big" or is someone else pulling the strings'
