Sol Madrid

An undercover narc takes on the Mafia in this "neatly crafted thriller" (The Motion Picture Guide) from director Brian G. Hutton (Where Eagles Dare), starring David McCallum, Stella Stevens, Telly Savalas and Rip Torn. When mob accountant Harry Mitchell (Pat Hingle) steals $500,000 from The Family, Interpol assigns agent Sol Madrid (McCallum) to find Mitchell and persuade him to testify. Discovering that the ex-mistress (Stevens) of mob boss Dano Villanova (Torn) has half the stolen money, Madrid blackmails her into taking him to Mitchell, who's hiding in Acapulco. Posing as a heroin smuggler, Madrid is welcomed by the drug lord (Savalas) with whom Mitchell is staying, unaware that Villanova is enroute and plans to deal with the thieves himself.
