Armand drives through the snowy Kansas City streets, pondering how he’ll have to retire from the detective force once he tells his boss about his cancer diagnoses. Next to him sits a cat in a box. He thinks about the Dollmaker, a serial killer who hasn’t been caught yet. Near the bodies of each of his all-female victims, the Dollmaker leaves a tiny doll modeled after the woman.

Four nights prior, Armand talks with Lamar, a young boy who owns the cat. Armand tells Lamar that he found the cat with the Dollmaker’s latest victim, in the trunk of a stolen white Toyota.

In the present, Armand ponders how the other detectives thought they could use the cat’s microchip to identify the cat’s owner and subsequently the killer. He thinks about the toll cancer is already taking on his body.

Back with Lamar, Armand explains he has to keep the cat at the police station as forensic evidence. He asks Lamar if he’d noticed the white Toyota parked near his house. Lamar remembers the car, but not the person who drove it.

Later that night, Lamar remembers the car owner was a man with missing fingers on one hand. He races to tell Armand in the morning. With this new clue, Armand knows the Dollmaker is a nurse named William Steingart.

Armand and a fellow detective question Steingart the next day. Steingart admits nothing, but smiles throughout the interview. They gather no proof.

Back in the present, Armand thinks about how just that morning another victim was found dead with a doll. Knowing Steingart is the Dollmaker but frustrated by his inability to prove it and fueled by his inevitable retirement anyways, Armand drives to Steingart’s house and confronts him about the murders. After Steingart admits to being the Dollmaker, Armand puts him in the back of his trunk. Lamar's cat meows in the box beside him.
