Útěk s Cézarem(1990)

Caesar is the name of the dog with which a little boy, only seven years old, sets out on a great quest to find his mother. She once gave him the dog before she emigrated. The boy does not agree with his father's intentions to remarry, even though the new mother is supposed to be a sympathetic governess from a children's sanatorium. The film was made at the very end of the former regime, but it was not released until the changed political situation.
