Mikko "Peltsi" Peltola and his 12-year-old son Osmo shake off the dust of the city and head off on a nature adventure. The journey takes them to the wilderness and Finland's magnificent national parks. Sometimes adventures are just around the corner! Osmo's down's syndrome adds its own colour to the adventure. What does an experienced nature enthusiast want to show and teach to his son? And what has Peltsi learned from Osmo? At least that everything can be a little more relaxed!
