Higgins and Magnum are hosting a party attended by some of Robin Masters' friends and Robin is suppose to arrive. But then a hurricane strikes and some people; a couple of criminals and a pregnant woman who's about to give birth show up. While Higgins tries to help the woman. Magnum tries to take care of the guys. And he is also trying to find out which one of Robin's guests is there to kill him.
