A seasoned criminal announces that he'll take on One Last Job before retirement to peaceful honest life. The possible reasons are many: they're tired of the risk and violence, they want to marry without dragging their sweetheart into their dangerous lifestyle, they want a big score so they can put their feet up in comfort, etc.
Usually, this leads to either a 10-Minute Retirement, or death by Retirony due to either a Plethora of Mistakes, his superiors deciding to show him there's only one way to leave their organization, or the universe deciding there is only one way back onto the straight and narrow. A frequently used variation with a more logical justification (and one that's probably more likely to stick in a non-fatal manner) is that this time, It's Personal.
In the case where the criminal actually manages to pull this off, they often go on to become a Retired Outlaw.
