The Memory of a Killer (2005)

His memory impaired by Alzheimer’s, veteran assassin Angelo Ledda (Jan Decleir) is appalled to discover his intended target is a 12-year-old girl. Refusing to kill her, Ledda breaks his contract, only to have his boss carry out the hit instead. Incensed, Ledda vows vengeance and sets out to find the man who ordered the child's death. Systematically wiping out middlemen and go-betweens, Ledda leaves a blood trail that is followed by Chief Inspector Vincke (Koen De Bouw), a police detective who's desperate to learn what links the dead girl with the most powerful men in Belgium. And so, with the cops one step behind him and his memory fading fast, Ledda finds himself in a race against time as he tries to avenge a child whose face he can no longer recall.
