Gun Shy (2000)

"The Agency's best has a bad case of nerves."

Legendary undercover DEA agent Charlie Mayough has suddenly lost his nerves of steel. On the verge of a career-induced mental breakdown, and in complete fear of trigger-happy Mafia leader Fulvio Nesstra, Charlie seeks psychiatric help and finds himself relying on the support of an unstable therapy group and nurse Judy just to get through his work.
