Beware of Children traces the dramatic aftermath of a tragic event in a middle-class suburb of Oslo. During a break in school 13-year old Lykke, the daughter of a prominent Labour Party member, seriously injures her classmate Jamie, the son of a high-profile right-wing politician. When Jamie later dies in hospital, contradicting versions of what actually happened risks making a difficult situation worse. Liv, the school’s principal and the secret lover of Jamie’s father, confronts the community in distress and her own conflicted emotions.
