Eider and Mikel, a young Spanish couple from the 1950s, are in a clandestine farmhouse with their friend Susana. She supposedly brings them objects from the United States, the country they both dream of escaping to.
Their fantasies are interrupted by the appearance of an unknown object that bursts into the farmhouse, shaking and emitting lights and sounds.
After going through several phases — confusion, fear, chaos, curiosity, exploration, and finally communication — they realize that the strange object belongs to Susana, who must explain everything to her friends while dealing with a complicated emotional situation.
