In Raya Martin’s thuggish fable of disengagement, a teenage girl grows distant from her parents before possibly vanishing altogether. But this is no angst drama. It’s defiance against a kind of ordered existence, treating death like a game, living life in a soft-focus daze, ready to evaporate if pushed far enough. The girl and all the other faceless kids wander numbly in slow motion through the brush, through the parental jabber, only the electronic drone keeping them from losing their bearings.
