Los Aliens (2021)

A jaded Border Patrol agent and his fresh-faced partner are bantering about the ethics of immigration when a comet rockets across the sky, and a call from base interrupts their conversation: Ground triggers have been tripped. Time to track down the interlopers. But they're not the only ones in pursuit: an alien arrived with that comet. Slender, androgynous, and child-like, it turns its wide eyes over the open desert, picking up the heat signatures of a migrant family: a mother, a father, and two young daughters. As the alien and the agents converge on the family, unknown to each other, a tense hideout turns into an explosive chase.
