Set on the shores of Lake Michigan, the title refers to a weather phenomena that piles up snow locally and across eastward. The movie begins with Ross Partridge character struggling both financially and in his personal life when his very pregnant somewhat-estranged daughter shows up while he's on holiday with his girlfriend in a stunning, secluded lake-front rental. And then the teen father-to-be shows up: four is definitely a crowd. The characters don't really have much in common but they do try; the movie goes from a farce to a rom-com with some really funny moments in between.
SPOILER ALERT: The film ends predictably with the teenage girl giving birth in hospital with complications and a whole existential ICU scene where you dont know if the baby will make it but everyone learns a alot about themselves in the process. (Just kidding! i just made that up... im not going to spoil it.)
