Mark vs. The Mountain

High-altitude construction meets high-stakes health as the Ronchetti's place their trust in perfect timing.

Mark and Krysty Ronchetti embrace a new calling: building a home atop New Mexico's highest peaks.

From broken bones to falling trees, the mountain fights back as the Ronchetti's race to beat the snow.

A broken water line threatens the foundation, forcing Mark to act fast to prevent a mountain flood.

The Ronchetti's pray over their finished dream home before handing the keys to the next lucky family.

With only four weeks left, a series of appliance and plumbing errors puts the entire project in jeopardy.
