When Mike Harper (John David Carson) comes to Hawaii and finds himself reliving a childhood trauma where he encountered Phil Coleman (John Ireland), a bank robber, he goes to a bar where Coleman, recently released on parole, is now working as a bartender, and freaks him out when he drops a name which Coleman hasn't heard for 20 years. Walter is another bartender or waiter who restrains Coleman.
Later, Jake Cochran (John Zenda), the boss of the restaurant, is talking to Walter's character.
