Wolfman Mac's Chiller Drive-In S02 E04 Attack of the Giant Leeches

Radiation once again plays the role of monster maker and turns some happy little swamp leeches into monstrous beasts that feed on humans - and make basketball sized hickeys on their victims. It stars Yvette Vickers, who was probably best known as Playboy's Miss July 1959 - Because this film sure wasn't going to make her a household name.
