Synopsis by Hal Erickson
Gilligan's Island becomes "Mystery Island" when the Castaways begin to vanish, one by one. Ultimately, only Gilligan (Bob Denver) remains, terrified at the prospect that he is somehow responsible for the disappearances. Can it be that our hero has transformed into a latter-day Dr. Jekyll and Mr. Hyde (as suggested by a surrealistic dream sequence?) No, the answer is more benign than that... but no less bizarre!
