The Whole Nine Yards

The wife of a dentist convinces him to betray their new neighbour - a hit man turned informant - to the Chicago gangsters who want him dead. In need of money in order to hurry through a divorce, the young man arranges a meeting with the Mob in which he will exchange information for cash, but when his scheming wife tells the hit man what he is up to, it is the dentist's life that is placed in grave danger.
