Black Widow

Debra Winger is great as always as the FBI backroom researcher allowed out for a change to pursue her theory that the widows of several millionaires who have all died of the same rare disease are in fact the same woman.

She finds herself fascinated as well as repelled by Theresa Russell's glamour, lifestyle and ability to use men for her own ends. Russell in her turn sees her as a worthy opponent (unlike all those men she takes in so easily).

In fact all the men are just part of the background to the play between Winger and Russell.

Its a terrific film all round and I may be alone in this, but I think the ending works.
