Gunnar (Viggo Mortensen) is a Danish military engineer in 19th century Argentina, brought on to help quell the natives. Along for the ride, and causing something of a stir among the Argentine soldiers, is Gunnar's 14-year-old daughter Ingeborg (Viilbjørk Malling Agger) — but when Ingeborg disappears, the ill-equipped Gunnar sets off into the unforgiving Patagonian desert to find her. With its hard, Mulholland Drive-worthy left turn in the third act, Lisandro Alonso's stark and puzzling film will be off-putting to some, but for those willing to get on its challenging wavelength, it's worth the ride.
