Anxieties of a 5-year-old

In Morrison Gets a Baby Sister, another film I translated for AleKino!, the world turns upside down for a 5-year-old Morrison whose parents announce the arrival of his baby sister. This means sweeping changes in the boy's priviledged position at the centre of the family and sensing this unfavourable turn Morrison takes action. He goes on a series of unlikely adventures, stealing his dad's car, which he'd been trained to drive, and kidnapping his newly born sister. Distressed parents almost go out their mind and the village community is roused to its feet to join the desperate search for missing kids. Funnily, the most outstanding helper is a clumsy village police officer, who keeps chasing cars and tractors on his motocycle just to let them go free with a mild warning, whatever their offense. These's no doubt at any point that we're waiting for the happy end and it comes indeed with Morrison bravely reestablishing his position in the family and falling in love with his new sister.
