Magnum P.I. S01E06 - Skin Deep

When a beautiful model-actress is killed by a shotgun blast in a scenario closely resembling a scene from the script of an upcoming film, it is seemingly suicide. Magnum is hired by her former producer and lover to investigate any other men that she may have been seeing before her death; a case that Magnum is reluctant to take, but, feeling guilty for not taking it before the girl was killed, agrees to.
