In 17th-century Latvia, as Swedish and Polish armies march across the war-torn land, the corrupt councillors of Riga stand ready to hand over the city’s keys to whichever foreign power pays the highest price. But three jolly friends — Andris, Pēteris, and Ērmanis — together with their female companions Rūta, Anna, and Lēne, refuse to surrender without a fight. Rallying the people of Riga, they rise in a courageous struggle for freedom of their city.
