Das Boot ist voll (1981)

During World War II, a group of refugees from Germany crossed the border into Switzerland in search of shelter. Since during the war, refugee families with children under the age of six were allowed to take refuge in Switzerland, the owner of an inn accepted the refugees so that they could avoid suspicion and be deported as long as they disguised as a family. One of the refugees spoke only French, while his "parents" spoke German. Can the child know how to keep silent when he takes everyone's fate into his own hands?
