In 1975, 15-year-old April Cooper and her 18-year-old boyfriend embark on a weeklong killing spree that results in the deaths of a dozen innocent people in Southern California's San Gabriel Valley.

In 2015, Robin Brennan's parents have been involved in a shooting. Her father is dead, and her mother in a critical state, with Robin desperate for her to wake.
