Smile, you’re on Castle Camera! A band called Holy Shemp (these guys must love the Three Stooges) is the focus of a documentary film. Recent footage contains images of their lead guitarist, James Swan, dead in his trailer. One of the roadies, Hank Rogers, lets Ryan know that the cameras have permission to film. Esposito gets similar information from the mayor’s office. As Beckett works the crime scene, Castle works the camera to let everyone know that Frozen Heat is in stores now. Gotta love product placement!

The victim has the word “observe” tattooed on his arm. The murder weapon was his classic guitar. A pretty groupie named Butterfly was passed out when the killing took place, but she heard the sound of horse hooves crunching in the snow at one point during the evening. More on that later. The team learns there was some tension amongst the band members and a white van was in the area. The band claims that James was paranoid that someone may have been following him lately.

Documentary footage shows James talking about a mentor who meant a lot to him. A bearded man can be seen in the background. He’s been photographed at other band events, too. One shot has him leaning against a white van. Esposito mugs for the camera as he and Ryan arrest the stalker suspect who has rope and duct tape in his van. Espo goes hard at beard man during the interrogation, but the guy’s no killer. He’s just Butterfly’s worried father who was just trying to rescue his little girl from the groupie life. The desperate dad lets the detectives know where the victim was just before his death.
