Prague-set tale centers on sensitive moppet Terezka (Dorotka Dedkova), whose favorite bedtime story is "Little Red Riding Hood," even though it gives her bad dreams. Her family consists of her loving but tightly wound mother (Jitka Cvancarova), a once-promising singer who put her career on hold; her warm but workaholic father (Pavel Reznicek); and her elegant, critical granny (Jana Krausova), who schemes to reunite daughter with her former boyfriend Patrik, a selfish virtuoso musician (Martin Hofmann). At kindergarten, Terezka and best friend Simon (Matous Kratina) excitedly share their growing knowledge, including important tidbits such as how to identify an alien. When another tyke lands a new sibling, Terezka becomes obsessed with whether her mother is really her mother, little suspecting the altogether different secret surrounding her parentage.
