In the greatest arm wrestling movie ever made, Sly Stallone stars as a long haul trucker trying to build a relationship with his estranged 12 year old son, while also trying to beat other truckers at arm wrestling. The grand prize for winning the truckers arm wrestling tournament is a new truck. Along the way, he teaches his son how to arm wrestle and drive a truck. Robert Loggia costars as the kid's wealthy grandfather and Terry Funk costars as Loggia's head goon, though it's not really clear why he would need goons. Great film.
