The Big Empty (2003) on Netflix

Would be-Hollywood actor John Person always considered his bizarre neighbor Neely a conspiracy theory nut-case. Still he accepts a simple task to wipe out his over $27,000 debt: delivering a blue suitcase to some Cowboy at Baker, in the empty desert. The place proves a nest of weirdos, including extremely jealous Randy and his girl Ruthie, who seduces John. He learns Neely was murdered, and FBI agent Banks grills him as prime suspect. Yet the weirdest is still to come once Cowboy turns up.
