Sometimes the bad guys get caught, or maybe the good guys are falsely accused. Whatever the reason, this trope occurs when a character is thrown in prison and undergoes some change while there. When they're finally released or break out, it turns out the experience has changed them fundamentally, perhaps teaching them important life lessons or just spurring them on to a life of crime. Often Played for Laughs if the character was only in prison a short period of time, yet still claims to have been irreversibly changed. No Real Life Examples, please!
