ABC's "Extreme Makeover: Home Edition" - Season Seven

EXTREME MAKEOVER: HOME EDITION - "Heathcock family" -- "Extreme Makeover: Home Edition" travels to Hattiesburg, MS - with Christian Slater as the celebrity volunteer -- to meet Sherman Heathcock, a devoted husband and father who re-enlisted in the Army National Guard following 9/11. Since that time he has served two tours of duty in Iraq, where he leads squads in combat missions. When he is fortunate to spend time at home, Sherman works several jobs, which leaves little time to repair the devastating damage to their home left by Hurricane Katrina. On this episode of Walt Disney Television via Getty Images's "Extreme Makeover: Home Edition," SUNDAY, MARCH 21 (8:00-9:00 p.m., ET), Ty Pennington and the designers will have the opportunity to give back to this soldier who has given so much to his country and his community.
