Buffy (Johnnie Whitaker) and Jody (Anissa Jones) are terrified when a Criswell-like TV psychic predicts that New York will be destroyed by a tidal wave. Though there are some otherwise responsible adults who swallow this story whole, Uncle Bill (Brian Keith) is not one of them, and he must work overtime to convince the twins that their fears are groundless. But when Bill suddenly has to leave New York, the kids jump to the obvious conclusion and the situation gets far worse than imagined! Watch for Erin Moran, four years away from her role of Joanie Cunningham on Happy Days, in a supporting role. ~ Hal Erickson, Rovi
