It's the summer of 1976, and Steven Paul is days shy of his seventeenth birthday, when he hooks up with his oddball friends for a day in their local West Austin, Tarrytown park. The plan is simple: the consumption of cold beer, cheap weed, and a large Conan's pizza.
All's well in the exclusive park when a seemingly frail bull terrier catches the boys' attention. This dog is an oddity, for stray dogs do not exist in this part of town. High and with their curiosity piqued by this abnormality, the boys feel compelled to investigate.
The timid and skittish dog leads Steven Paul into a ransacked house next to the park and onto a crime scene that sets into motion a string of events with far-reaching consequences.
