The film follows the pair as they head out in Louise's ethereal teal 1966 Thunderbird convertible for their journey that nosedives into a nightmarish situation before they even reach their destination, but which sees them change from victims of circumstance into outlaw heroes of the inner planes. Their actions continue to spiral out of control as the two of them make their way across the country, particularly with the ever-more-daring Aleister, who has shed his giggly, goofy personality for a determined, aggressive, homoerotic hard-drinking one.
