Greydog (2004)

When you spend most of your life in prison, getting released into freedom is more intimidating than you'd expect. But now Deke, Dub Dub and Karl face that challenge as they make their way back to the homes they're not even sure still exist. During their trip cross-country on the 'Greydog' bus, the men quickly learn that the lifestyles they grew accustomed to in prison have little application in the outside world. After living in a world where no one is to be trusted, the convicts' only hope is to rely on the strangers around them. The journey is a series of both comedic and tragic events that teach the men who they were, who they are, and who they will become.
