The story transports audiences into the world of 1960s Texas as Jake explores the multiple mysteries surrounding the alleged assassin Lee Harvey Oswald (Daniel Webber). But Jake's mission faces threats not only from Oswald, but from Sadie (Sarah Gadon), a beautiful librarian he falls in love with, and from the Past itself... which doesn't want to be changed.
