In the year 2424, it seems crazy that people once needed film to take photos. Max and Oscar – Bluggsville's smartest sleuths – are shocked when they find a 400-year-old roll of film. They're even more shocked to discover that it still seems to contain someone's happy snap! Unfortunately, they're not the only people who realise how rare, and valuable, this photo could be. Max and Oscar are going to need all of their wits to make sure the photo ends up in the museum, where it belongs!
