In the present day, Jack finds Tiller's photo in the book. An old man now, he received a Medal of Valor from the FBI. Jack and his pretty eyelashes seethe with rage. Cue the title card. Alcatraz!
In some unknown area of San Francisco, a man with a blond crew cut is chased across rooftops by another man and a woman. When his pursuer lands badly and finds himself clinging to eave, the blond man kicks him in the face. He struggles to hold on. The woman comes running along and makes a leap and a landing that should break her ankles, but she gets up and runs over to her partner. For a moment, the blond man stares at her with wide-eyes, then keeps on running. She tries to help her partner back up onto the roof, but he slips and falls a long, long way down. She stares in horror.
"Madsen," a man's voice says. Now she's sitting in an office, staring into space. "Detective Madsen!" She blinks and forces herself to pay attention to the present. She looks very young. She has a Kara Thrace blond bob that says, "I'm spunky and tough, but secretly vulnerable!" The man calling her name is her lieutenant and it's been three months since her partner died. They don't have any leads on the man who killed him, so the lieutenant says it's time to move on. That doesn't sound like something a cop would say regarding the murder of another cop. The lieutenant offers her a list of possible new partners, but none of them sound right to her. She's saved from making an immediate decision when someone interrupts the meeting to say that Madsen's wanted on a homicide call.
Crime scene. Tiller lies dead in the shattered remains of his glass coffee table, a knife plunged into his heart. (He should have known he was done the minute he bought that table. People who own glass tables always come to a band end on TV.) One of the cops on the scene, played by super cute Santiago Cabrera, fills Madsen in. He tells her the vic was a fed, which is her cue to hurry up and gather up as much evidence as possible before getting booted from the case. She notices a picture that's been knocked over on a shelf. It's from Tiller's younger days at Alcatraz. Sam Neill walks in and tries to shoo Madsen away. He introduces himself as Emerson Hauser, but that doesn't mean anything to Madsen, so she gives him lip about not taking orders from him. Right on cue, she gets a call from Lieutenant Reeger, telling her to scram. On her way out, she asks Santiago -- er, Jimmy -- to run Emerson Hauser's name through the database. Couldn't she do that herself, being a detective and all? Maybe she's too busy stealing that picture from the crime scene. What a great way to screw up a case, lady.
