Magnum is surprised when a beautiful English woman spurns his advances - much to the amusement of T.C. and Rick - instead preferring Higgins. Magnum is certain that the woman is feigning interest in Higgins only to somehow use him and plans to uncover the truth, but Higgins sees his doubts as sheer jealousy, and the ever volatile relationship between the two is pushed towards breaking point.

Magnum is asked by the ex-wife of the adventure-seeking author "Mad" Buck Gibson to keep him out of harm's way until she collects the alimony he owes her. But, this task proves to be difficult as Magnum learns that "Mad" Buck is harboring a secret that could be the reason for his self-destructive behavior.
