Although released in some markets during the fall of 2008, it was released straight to DVD in the United States on March 24, 2009. It debuted at number 17 on the DVD rental charts of March 23–30, 2009.

Stan Minton is a wealthy real estate con artist who is married to Mindy. One day, he is arrested for conning elderly people out of their savings. His lawyer Mal defends him at the trial presided over by Judge Perry. The jury's forewoman reads the guilty verdict and the sentencing will be the following day.

While talking with Stan, Mal refuses to bribe Judge Perry since he does not practice that kind of law and tells Stan that any shyster on the street would do it for him. Inspired by the bench advertisement outside, Stan fires Mal from the case and hires Lew Popper as a replacement for the sentencing. Judge Perry sentences Stan to three years at the Verlaine Correctional Facility, while giving him six months to reorganize the charity that he had established to teach music to mentally disabled children.

As he cannot go on a permanent vacation to Brazil on Lew's advice due to his assets being frozen, Stan gets drunk and visits a biker bar where he has the fear of jailhouse rape instilled in him by a biker ex-con that strains his marriage to Mindy. Stan decides to learn self defence to protect himself against other inmates, and initially fails to learn at a dojo run by Master Cho. Stan is approached by a mysterious guru known as The Master who helps transform him into a martial arts expert. He passes every training and bests Master Cho. Upon Lew telling him that he has been reassigned to Oaksburg Correctional Facility, Stan gets himself processed for prison with the Master and Lew seeing him off. A tearful Mindy watches from afar.

During his imprisonment, Stan befriends an elderly inmate named Larry who is serving a life sentence for murdering his partner. Stan also encounters a sympathetic prison guard named Bullard and learns more about the cliques and gang activities inside the prison. He then uses his new-found skills to bring peace and harmony to the prison yard by intimidating his fellow inmates like Big Raymond into preventing them from harming each other. With this, peace is restored in Oaksburg and Stan gains their respect, eventually becoming their leader.

However, the corrupt prison warden Gasque has plans to force the prison's closure with a riot and sell off the property. While also encountering another student of the Master's named Dang, Stan helps Gasque with the real estate aspects in exchange for early parole. However, his peacemaking efforts threaten Warden Gasque's plan for a riot and he is persuaded to bring back violence.

In a last minute attack of conscience, he deliberately blows the parole hearing to rush back to the prison. He defeats Dang in combat, and prevents the deaths of his fellow inmates, only to discover that his message of peace has sunk in and the prisoners are dancing instead of fighting. Warden Gasque orders the guards to open fire on the dancing men. When they refuse, he grabs a gun in front of the board of governors and shoots outrageously. Warden Gasque attempts to shoot Stan, but he is stopped by Mindy and the Master who had snuck in. Stan was surprised to learn that the Master had trained Mindy during his incarceration when he thought they were having an affair during an earlier conjugal.
