Cole receives a disturbing call from Lutz, who believes Walsh knows he killed Kowalski and is on his way to Walsh's diner. Lutz poses as a customer and strikes up a conversation with Walsh before pulling a gun and firing. Lutz escapes and Walsh discovers that one stray bullet went through the diner into his apartment, striking Beaumont. Cole fears for his future as Walsh and Casey begin to uncover pieces of his past relationship with Lutz. Meanwhile, Banks continues to be haunted by the number 42 while he and Delahoy investigate a string of bus robberies. One passenger, a clairvoyant, tries to help them catch the robber with her predictions, causing Banks to question whether fate can be stopped.

Casey and Walsh are placed on protection detail of a wealthy businessman, George Reed, who had recent threats made on his life. Responding to screams they hear, they leave their post in front of Reed's hotel room and, when they return, find his room is trashed and him gone. Then a ransom call is made asking for $10 million for his safe return. Meanwhile, Banks and Delahoy are put on the case of an 87- year-old man on a geriatric crime spree.
