Chesty gringo Telly Savalas (as Frank Cooper) is a US-Mexico "Border Cop". He serves as a father figure to young immigrant Danny de la Paz (as Benny Romero), who wants Mr. Savalas to be best man at his impending wedding. Savalas is tough, but boss Eddie Albert (as Commander Moffat) may be tougher. Tough is what you need to stop smuggler Michael V. Gazzo (as Chico Suarez). Alliances may be in flux.
