Overview: When a pressure spike causes a cave in and brings the rig to a screeching halt, Oscar steps up to the drilling slot to keep the rig running. A visit from his family reminds him of what is truly at stake. With their competition to become a Big Dog driller on hold, Mitch and Cheston have a spitting contest of sorts - roughneck style.

And a heart to heart with his father brings Brandon to tears - and closer to the root of his anger issues.
