Volunteers (1985) (Tom Hanks, John Candy)

Lawrence is a rich kid with a bad accent and a large debt. After his father refuses to help him out, Lawrence escapes his angry debtors by jumping on a Peace Corp flight to Southeast Asia, where he's assigned to build a bridge for the local villagers with American-as-apple-pie WSU grad Tom Tuttle and beautiful, down-to earth Beth Wexler. What they don't realize is that the bridge is coveted by the U.S. Army, a local Communist force, and a powerful drug lord. Together with the help of At Toon, the only English-speaking native, they must fight off the three opposing forces and find out what is right for the villagers as well as for themselves.
