An artist paints a portrait of Maddie (entitled "Charlie's Treasure"), whom he has never met, and then commits suicide. She is called in for a questioning. Maddie buys that painting and later gives it to the artist's brother Charlie, only for him to also die. It turns out that nothing is as it seems to be and that the painting is a clue leading to the whereabouts of a famous painting that was stolen by a gang three years ago from an art gallery in Paris. That leads the duo in a hunt for lost paintings, ridiculous chases, fights and an unexpected climax in an Auto Shop next to the painter's apartment.
