Nelly spots Ricky on the street and tries to shout at him, but he can't hear her and disappears around the corner. Aunt Serena is surprised to see Ricky in the shop, exploring the candy shelves, when she should be at home vacuuming. Downstairs neighbour Lennart Lindberg asks Ricky to go fishing, but he never shows up. Is there a Ricky look-alike in town? And if so, where and why has he come to the neighborhood?

Serena Rapper gets a strange prediction: a genius has been born to her immediate family. When Serena finds a drawing Ricky has made, she is certain that Ricky is Vincent Van Gogh reborn. She decides to show Ricky's drawing to the intendant of the Art Museum. At the same time, a sketch of one of Van Gogh's paintings is found in Finland! This discovery starts an exciting chain of events, and in the end, the janitor of the Art Museum, a keen amateur detective, helps Ricky and Nelly to solve the mystery.
