A soldier learns how war breeds injustice in ways he didn't imagine in this drama from director Aku Louhimies. It's 1918, and Finland is caught up in a civil war as the "Reds," supporters of a Social Democratic faction led by the People's Deputation of Finland, battle for control of the nation against the more conservative allies of the Senate, known as the "Whites." Aaro (Samuli Vauramo) is a soldier fighting with the Whites who has captured an angry woman (Pihla Viitala) who was helping a Reds faction. Aaro brings the woman to a military tribunal overseen by Hallenberg (Eero Aho). Aaro is confident that the woman will receive a fair trial, but Hallenberg soon reveals his prejudices, and Aaro isn't certain how to confront a superior officer about a possible miscarriage of justice. The situation is complicated by Aaro's growing affection for his prisoner, as well as Hallenberg clear but undeclared attraction to Aaro. Kasky (aka Tears of April) was adapted from a novel by Leena Lander, which was previously brought to the screen by Dome Karukoski under the title Home Of The Dark Butterflies.
