His superior is Fletcher (Ernest Borgnine), a drug enforcement officer with shady business contacts. Wesley and his crew, including the tough Charlton (Klaus Kinski) and China (Lee Van Cleef), head out into the jungle to eradicate the drugs at their source. Battles and explosions follow. ~ Eleanor Mannikka, Rovi
