10 year old Oskar has a dream. He wants to ride the prairies with his mother. Right before summer vacation, Oskar’s mum tells him she is going to America, while he has to stay behind on the farm with his bad-tempered grandfather. Fortunately for Oskar, he gets acquainted with Levi and his short-sighted horse. Together they set up a nutty plan to cross the Atlantic Ocean in a rowboat with Levi’s horse as a passenger, in order to find Oskar’s mum.
