While on vacation in Poland, Bethany breaks away from a romantic itinerary planned by her doting boyfriend, fearing that a marriage proposal is imminent. When she reunites with Nel, an old friend, the two women rekindle a uniquely combustible chemistry over the course of a few days.

Explosive, lava-hot desire—and a literal volcanic eruption—threaten staid bourgeois routines in this stylish force-of-nature romance. Revealing the dramatic talents of zeitgeist-catching singer Charli XCX (who stars), Erupcja burns with all the yearning of an endless summer’s night in Warsaw.
