The most popular rumor in SHIELD was that Agent Phil Coulson was created in a lab. The rumor was unproven. It was also true.

When he takes the rap for a crime committed by Barney and the Swordsman, Clint is charged as an adult at 17 and spends the next four years of his life without protection in prison. Enter one Neal Caffrey, who knows how to charm his way to whatever he wants or needs, and Clint's life gets a lot more interesting. Pretty much, the story of Clint in prison, Clint getting out, and Clint, like always, finding his way to SHIELD, and Phil.
