When Lionel learns by chance that his family originates from Poland, a chain of events is set off that will change his and his sister Lucie's lives forever. Brother and sister make their way to Eastern Europe in a “borrowed” car from the Swiss Radio, not completely sure if they are descendents from a Polish family. However, getting involved in a car chase in Slovakia is a sure thing, as is the stolen car, the white wedding, and false passports. The road to Warsaw turns into the adventure they've been longing for. And somewhere in Poland, a horse drowns every night.
