Jacob lives in the city and dreams of becoming an architect like his father. One day, when his dad has to go away for work, Jacob spends the week with his cousin Mimmi and her father. They live in the suburbs of Riga, Latvia’s capital. There everything seems different and calmer. When the boys realise the local park will be replaced by skyscrapers, they will try to stop the construction. And they will get precious help from a pack of special dogs.
