James Van Der Beek guest stars as a disgruntled ex-boyfriend who gets his vengeance on the man he believes stole his college girlfriend, Colin Barnes, by seducing the daughters he conceived by donating sperm. The detectives discover his crimes when they locate several young girls who thought they found their donor-father, but actually met with Van Der Beek's character Sean. Sean uses the girls' desire for a father to manipulate them into having sex with him. However, his biggest revenge is seducing and apparently kidnapping the Barnes' daughter. He tortures the couple by refusing to tell them where she is and then says he killed her. Luckily, the detectives find her at a hotel, but she won't believe the truth about Sean.
