Mijn vader woont in Rio (1989)

Lisa's parents are separated. Like the title says, her father (supposedly) lives in Rio de Janeiro. She often gets letters from him and dreams of visiting him in South America one fine day. However, this is all a major cover-up: the father is actually in a Dutch jail for a very long time. On top of that, her loving grandfather recently passed away, and there's no chemistry whatsoever with her mom's new boyfriend. Lisa can't take it anymore and runs away from home... to Brazil.
