In WYWO's largest ever space, they're about to tackle another first - an underground home. Diana and Ed live in a former missle silo, beneath the Kansas City plains. The couple uses the area as a sacred temple space and would like to continue to do so, but Ed wants to give it an extra touch of flair for Diana.

Battling time and budget constraints aren't the only challenges for Nadia and the team; they also battle wind and wildfires. This will definitely be an episode for the books, but will the team finish in time?
