Stuck in the Arizona desert on an abandoned airbase, Lia has lived a sheltered life alone with her borderline-schizophrenic father. But her weird life is offset when two strangers arrive in the desert and take a keen interest in her home. Lia can't help but feel a new-found confidence when the odd duo ask for her help to show them around - but are they really just curious tourists, or is there something they're not telling her?
