Black Widow

She mates and she kills.

A tense neo-noir thriller about a federal agent's dangerous cat-and-mouse game with a calculating serial killer, built on deception, obsession, and the blurred line between hunter and hunted.

Federal agent Alexandra Barnes believes that Catherine Petersen is a serial killer who marries rich men and then murders them for their money. But since Catherine is seemingly a master of disguise and has multiple identities, Alexandra can't prove anything with conventional detective work. With no other option, she goes undercover, pursuing the same man as Catherine, and hoping that Catherine will slip up and reveal her true identity.
