Zach's Lie (1970)

Jack Osborne's life changes forever the night men in masks break into his house, threaten his family, and ransack their home. Jack, his mother, and his sister are then forced to enter Witness Security Program. Jack becomes "Zach" and moves to Elko, Nevada, a town in the middle of nowhere. There he meets Sam, the strangest school custodian he has ever encountered, and Catalin, a girl who might make Zach's uprooting worth the trouble. But just as Zach finally begins to piece together a new life, he finds himself in danger again-and this time his actions could determine the fates of everyone he cares about.
