It's 1971, Toronto. Hal Sachs runs a used bookstore, which is about to be paved over with a behemoth expressway. When Hal meets Lily Klein, an activist schoolteacher who'll do anything to stop the highway, it's love at first sight. Then Hal vanishes. A half-century later, Hal's nephew, Aitch, tries to piece together facts and fictions about Hal's disappearance.
