An unnamed character had grown up with Kat. She reflects on Kat's life through the photographs she has of Kat's life.
Kat had grown up in the early nineties in Chicago. She had attended an all-girls high school and spent most of her free time making music with her guitar. In the photographs, Kat plays the guitar in the basement of her parent's house in high school; older, she looks over the heads of the crowd as she performs onstage; she dates a guy named Giles and their relationship blows up.
More scenes of Kat's life, documented through photographs, spill by as the photographer remembers them. Kat tours with her band and uses drugs to stay alert. Kat calls home to a father who doesn't remember who she is. Kat pukes endlessly over a toilet in a bleak apartment.
One of the final photographs depicts Kat clutching pills as she lies on a bed in the ICU. She is dying of cancer.
In the wake of Kat's death, the photographer hopes that by getting all those photographs, by documenting Kat's existence on Earth, she has somehow made up for everything she had neglected to give Kat while she was alive. She wishes that she hadn't been just a big camera that looked into Kat's life, a camera that kept asking for more.
