Jerry Digby knows something is wrong that winter afternoon in 1978 when the estranged father he hasn’t seen in months shows up in front of his school, drumming his fingers against the steering wheel with a cigarette in his mouth, promising adventure for Jerry and his little sister. Something isn’t adding up. Riding in a rusted ice cream truck, the three leave California with the remains of their father’s friend packed with them after a botched backyard cremation. While their journey ultimately leads them into the teeth of one of the worst blizzards to ever strike the east coast, the storm outside pales in comparison to the storm brewing inside, as their father unravels with each passing mile, leaving Jerry and Faye vulnerable and very much in trouble.
