Watch FilmoFlix. ​An American hiker, Jack, takes an elderly couple, Björn and Áslaug, hostage in their remote summer cottage in the countryside. Jack believes that Björn is his father whom he has never known, the result of a love affair in the United States. Björn and Áslaug must contend with Jack's unpredictable behavior as they face painful secrets from the past. Jack's demand for a DNA test and his increasingly violent behavior force Björn to spin desperate lies, while Áslaug conceals her own involvement in the dark past that connects them all.
