When Iris moves to the Czech Republic to explore her heritage, she knows she might not be accepted because she's half German, but she has no inkling she's about to become embroiled in a plot to retake the borderlands. Tree farm owner Mikuláš is finally ready to put the past behind him. Dancing to old Bohemian folk tunes with Iris gives them both a chance to grow. But when his friends and neighbors start to die, their homes snatched up, hectare by hectare, Mikuláš knows he has to fight to save his land – and his life. A stream with a clump of plum tart iris growing on its banks. It binds them together. It tears them apart. Will the past finally flow into the future?
