A heavily indebted construction entrepreneur (Tom Pöysti) robs a bank in Jakomäki, Helsinki. He takes two officers (Jonna Järnefelt and Stina Rautelin) and one customer (Dominic Landon) hostage from the bank. In addition to himself, the desperate robber threatens to blow up the hostages if the police who left to follow them try to prevent the escape.
It's the most exciting moment of the year: Easter night and little Mimosa birthday. Muskotti, her mother, has such a bad memory that she doesn't know how old Mimosa is. Mimosa's birthday is a warm and fairytale-like film, but at the same time a sneaky story about a girl's growth into adulthood. It takes place entirely in a wizarding world awash with a night blue glow.
