Gun Shy(2000)

Charlie, a legendary undercover DEA agent, has suddenly lost his nerves of steel. Although he's been involved in more drug busts than he cares to remember, his instinct for danger, his cool composure and his iron guts--especially his guts--have finally failed him. The post traumatic stress of his latest well-planned sting operation that went awry has shaken him to the core and he is now begging for retirement from his clandestine business. However, Charlie is in too deep and has to fulfill one final complex covert obligation. 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.
