Krysantemum follows a young man called Anders (played by Morten Hee Andersen), who is involved in illegal firework sales. Anders must make amends with his father, Thomas (Henrik Birch), whom he hasn't spoken to for years following a tragedy, as they try to save their family farm. The film has been described as an “explosive” family drama that presents an emotional and thrilling look at a family involved in illegal transportation and sales, and their search for forgiveness. Karen-Lise Mynster (The Butterfly Swing, the TV series When the Dust Settles) plays the role of Anders' mother.
