With both Bill (Brian Keith) and Mr. French (Sebastian Cabot) out of town, Cissy (Kathy Garver) is placed in charge of the twins and the household. When her boyfriend Gregg (Gregg Fedderson) invites her to attend the Winter Carnival in Dartmouth, Cissy arranges for a baby sitter to look after Buffy (Anissa Jones) and Jody (Johnnie Whitaker). Only after Cissy is long gone does the sitter call to announce that she can't make it, leaving the terrified twins to baby-sit each other throughout the long, long night--which threatens to get even longer and more terrifying when a blizzard hits New York, preventing the rest of the family from returning home!
