Nick and his pal Clifford, the red clue-hunting dog, are friends for life who will never leave each other's side or ever grow old. Together they find clues, help their friends, and solve crimes. Crimes such as growing old. Nick has learned much about the dangers of growing old and how it eventually leads to literally graduating from life. Growing old sucks and, frankly, terrible for ratings, which is exactly why it's banned. Beep. Boop.
