Volunteers (movie, 1985)

After his rich father refuses to pay his debt, compulsive gambler Lawrence Bourne III joins the Peace Corps to evade angry creditors. In Thailand, he is assigned to build a bridge for the local villagers with the help of American-As-Apple-Pie WSU Grad Tom Tuttle and the beautiful and 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 themselves.
