Storyline

Unemployed math genius and social cripple Noah Valiquette (32) is shot in a park by a clown who cut off his right index. Suspects abound due to a circus movie audition. After his widow reports the house ransacked, it appears the finger was the key to a safe, but the robber failed to realize the treasure was a spa locker-room key, hidden in a cheap chess set. It was a universal code hacker, ordered by Noah's partner, Toman Bundiger, from Noah, a Dutchman and closed psych ward patient Oliver McDaniel, who escapes once told about the key.

Trivia
