Purple Hearts is a systematically simple love story set against the Vietnam War, with the action largely overwhelming the romantic time-outs.Ken Wahl is a handsome young and dedicated doctor in Vietnam where he meets a beautiful young and dedicated nurse (Cheryl Ladd). They fall in love. Between kisses, they assure each other that they hope one day to return Stateside and do medical good together forever. But then he’s killed – but no he isn’t – and then she’s killed – but (fill in the blank) – and it looks like they may never live happily ever after. Wahl is solid in the lead and Ladd hangs in there in a less demanding part.
