Ellen and HGTV's Cousins from "Cousins Undercover" surprised military veteran Mark and his wife Alicia with a home makeover. Mark lost both of his legs in the war, and still gives back to the community by volunteering to help other wounded soldiers. He even started his own non-profit organization. They just bought their home and it needs a lot of work. Cue Ellen's friends, the Cousins Undercover, John and Anthony, who are going to turn their house into something amazing!
