In 1946, resistance member Joop Hollebrands reported the abduction of two children to the police in Haarlem. Bert and Marleen Sanders went into hiding with him and his family during the war. It is the beginning of a chilling search for what happened to the pair, their sister Elly and their parents David and Clara. Eighty years later, Joop's daughter Corrie still cries when she tells how Bert and Marleen were dragged away before her eyes by a Dutch SD police officer in 1943. The arrest is the work of the infamous Colonne Henneicke, Dutch bounty hunters who scour the country in search of Jewish victims.
