Robin Zander - In This Country (Over the Top)(1987)

Lincoln Hawk (Stallone) is a struggling trucker who arm wrestles on the side to make extra cash while trying to rebuild his life. After the death of his wife, he tries to make amends with his son who he left behind 10 years earlier. Upon their first meeting, his son does not think too highly of him until he enters the World Arm Wrestling Championships in Las Vegas. His hope is to receive the grand prize of $100,000 and an expensive current custom semi-truck and thus start his own trucking company.
