Magnum, P.I. - Season 3 Episode 9 : Mr. White Death 1988

Magnum, Rick and T.C. are at a wrestling match to try and collect some betting money owed to Rick, when they find themselves in a tight corner up against some heavies, but they are helped out of the tight spot by ageing, cheerful wrestler Earl. When their new acquaintance - a former boxing champion who now wrestles in down-and-out clubs - learns that Magnum is a Private Investigator, he asks him to find him son, whom he was forced to leave many years ago. Higgins finds that he indirectly knows Earl through an old war friend, and the pair strike up a friendship, but as Thomas searches for Earl's estranged son, it begins to seem that elements of Earl's story do not completely add up...
