From Italy's Umberto Lenzi ("City of the Walking Dead") comes this creepy outing in which two teens investigate a weird transmission they hear on their ham radio. They trace the signal to a haunted house that's looked after by a deranged groundskeeper. More scary activity, including the ghost of a young girl and faucets that drip blood, await them and other unwary passers-by. Lara Wendel, Greg Scott, and Donald O'Brien star. AKA: "La Casa 3." 91 min. Standard; Soundtrack: English.
