Dear mr Q

13 year old Sigrid has a peculiar pen pal, Mr. Q, to whom she writes letters to. She pours all her worries and joys of everyday life into those letters. One day a little girl appears and claims that she is Sigrid’s half sister. She demands that they must help „rescue“ their grandmother from the retirement home. Sigrid is rather reserved by nature and suddenly she gets pulled into a real adventure. With joint forces the sisters manage to bring their grandmother home and what's maybe even better - reunite Sigrid’s parents again.
