Gunny Sam Harper is a career marine whose ability to focus intently on the job in front of him, has enabled him to survive a year of fighting in the Iraq desert. He's focused on getting his job done and taking care of the men in his unit. A quick trip home to Hattiesburg, Mississippi shifts his focus just slightly, but he's still on mission. Throw in his brother, Simon and his well-meaning brother-in-law, Hank, both of whom can't seem to stop butting into his life. Next add Riley Middleton, National Guard nurse, to the mix. Three men and one woman, all with the same goal, saving Sam Harper.
