When the ambitious federal investigator Alexandra 'Alex' Barnes (Debra Winger) reads the cases of two wealthy men that have just died and left their fortunes to their younger and younger wives, she suspects that the woman might be the same. She believes that the woman might be killing the millionaires without a trace to inherit their fortunes.

Alex travels and tracks down the mysterious female inheritor Catharine Petersen (Theresa Russell) but she finds nothing about her identity. Alex believes that the Catharine might have traveled to Hawai and she takes vacation to follow her instincts. Alex finds and befriends Catharine in the hotel and becomes close to her. When Alex meets Catherine's boyfriend Paul Nuytten (Sami Frey), she has a crush on him. Will her passion for Paul and her friendship with Catharine jeopardize her investigation?

"Black Widow" is an unforgettable neo-noir of the 80's, with the sexy and gorgeous Theresa Russell and Debra Winger playing a cat-and-mouse game in the lead roles. This film is one of my favorite from the 80's and slightly recalls "Body Heat" from the early 80's. In those years, Theresa Russell was one of the sexiest actress of the cinema industry and the role of Catharine Petersen is tailored for her. Unfortunately the Brazilian DVD has no Extras. My vote is seven.

Title (Brazil): "O Mistério da Viúva Negra" ("The Mystery of the Black Widow")
