Minnie's not too keen on sharing her already tiny room with her gran when she arrives from Nigeria. However, worries about floor space and how to open the wardrobe door are quickly replaced by more serious concerns. Gran is upset. She picked up the wrong suitcase at the airport and she's convinced it's a bad omen. And it almost seems like she's right when their flat is burgled and the only thing that is taken is the suitcase. The police aren't interested but Minnie and her friends know there must be a reason behind the burglary. There's a mystery and it's up to them to solve it.
