Prelude to "Emeralds are NOT a Girl's Best Friend". Magnum P.I. crossover episode.

For an upcoming charity auction organised by Higgins and an attractive socialite, to be held on the Estate, Robin Masters ""donates"" Magnum's services, to provide security over the valuable antiques up for auction at the event. Meanwhile, mainland Private Detective brothers A.J. and Rick Simon have been hired to steal back a Ki'i - a stolen Hawaiian artifact - by it's previous owner, who is in rapidly decreasing health and believes that he has been passed on a curse from which he will die, unless the Ki'i is returned to it's intended location of rest within the Hawaiian islands.
