Two girls disappear from a playground and the two best detectives in the police force try to solve the case.

Águst Guðmundsson directed this Icelandic period drama, adapted from the short story We Must Dance by William Heinesen, and set on an island in 1913. Pétur (Gunnar Helgason) narrates, recalling the days when mainlanders arrived for a wedding. Flirtatious Sirsa (Pálína Jónsdottir) marries Harald (Dofri Hermannsson), son of a wealthy landowner on the island. Offshore, a ship is sinking, so the men form a rescue party, returning with the captain, the engineer, and several sailors. With a storm gathering, the engineer dies. The clergyman requests an end to the festivities as a mark of respect. Sirsa protests, but her new husband brings the celebration to a halt. The group then fragments into different activities, drunken or otherwise, and the sensual Sirsa directs her attention toward the handsome Ívar (Baldur Trausti Hreinsson). The film's score features traditional folk music.

Five friends gather for a celebration that spins wildly out of control. Something goes terribly wrong. Next morning, national sports icon, swimmer Gulli Björns wakes up beside the naked body of a woman. No one knows who she is. No one knows where she comes from. Not his girlfriend. Nor his best buddy. No one remembers what happened. Now, as the questions fly fast and furious, Björns must wander through a mirrored maze of half-truth and full-blown lies to discover the shocking truth in a swirl of deception, manipulation and murder.
