Michel Franco’s Sundown is unsettling tale of existential drift, one that upends the way in which the concept of family is often thematized in narrative films. It’s now given a suitably eerie trailer by its distributor, Bleecker Street. The story involves a brother (Tim Roth) and sister (Charlotte Gainsbourg) vacationing at a Mexican resort when sad news arrives from abroad. The sister leaves, the brother stays, and the film’s mysteries concern the brother’s inscrutable motivations. Spasms of violence are expected in any film by the New Order director; those are hinted at by the trailer’s concluding sequence of flash cuts and bloody surf.

Sundown is in theaters January 28.
