Postal worker David Arquette ("3,000 Miles to Graceland," "Ready to Rumble") takes in a stray dog that turns out to be a champion FBI drug-sniffing dog that has escaped from the Witness Protection Program. A crime lord has taken out a contract on the talented pooch, which throws the life of the postman into chaos just as he is trying to impress the woman who lives across the street from him. The cast also includes Michael Clark Duncan ("Cats & Dogs," "The Green Mile") and Paul Sorvino ("Bulworth," TV's "Law & Order").
