It’s the middle of the Thirty Years’ War and Riga, then a free city, is fighting both the Swedish and Polish armies. The city council is torn by doubts as its two main spiritual leaders – the head of the Catholic Monastery of Maria Magladena and the head of the Lutheran Protestant Church – vie for power and influence. The regional nobility also has an interest in Riga. Despite treachery and indecision within the city council, three of Riga’s defenders – young, brave and fierce – deliver one surprise blow after another to the attackers, fall in love and happily escape certain death against all odds.
