Synopsis: Fry falls in love with a woman who too was frozen on New Years Eve of 1999 just like Fry was, but she recently moved to New York from Boston. The woman comes to work at the Delivery Service and Leela gets suspicious of her. But Fry wouldn't listen to her when she says she's no good for him. Also, Fry assumes Leela is jealous of his new girlfriend, too. So she sends Bender to go incognito to follow Fry and his girlfriend where ever they go. Professor Farnsworth then announces he invented a tracking device the picks up dirt on criminals. Fry and his girlfriend also go to dinner and movies together, too.
Leela and Bender take the device and do a background check on Fry's girlfriend only to find out she's one of those 'Black Widow Spider' vixens. They also learn that she tracks down a man she falls in love with, makes up a history about herself similar to the man's she falls in love with, and goes out with them. And after a while, she kidnaps them and poisons them. After they call the police about her, it's Leela and Bender to the rescue!
Fry's girlfriend eventually kidnaps him by taking him to her apartment and she's about to kill Fry. Leela and Bender also use the tracking device to find out where she lives. Just when Fry is about to get poisoned, he's saved by his friends. Leela and the police go after the girlfriend but she commits suicide by jumping off a high building and falling into a manhole and drowns. In the end, Fry feels totally dumbfounded for not listening to Leela's and Bender's doubts about her. Although he's heartbroken he gets on with his life. He also vows to listen to Leela next time.
