It is the fall of 1973 and 16 year old Madeline and her 14 year old sister Daisy move with their recently widowed father to Cape Cod from D.C. Everything seems fabulous in this idyllic beach community until one night Madeline and her high school friends sneak out to an underground disco and there they see something that will change their lives forever. This very 'different' night catapults into a series of momentous life-changing events that forces the girls to find a way to hang on to life with their dad. Maybe Dad isn't so bad after all.
