Jobless and unattached, 30-year-old Tom Chadwick has lost his sense of self. But a mysterious box of curios might hold the answers -- however strange -- to the person Tom really is. The box, bequeathed to him by a great aunt he never met, inspires Tom to start investigating his lineage, and the clues lead to a world of unusual stories and characters in both England and the United States. The single-camera, documentary-style series is written by Christopher Guest and Jim Piddock and presented in the same manner as Guest's feature films, like "Best in Show " and "A Mighty Wind."
