Ax Men soars to new heights as a helicopter logging outfit enters the competition. At Pihl, Dustin tries to talk his father into coming back to work and Rygaard's greenhorn faces his fears when he must climb a 100-ft tree.

The mountain's men face the firing squad. Jimmy heads into uncharted waters, but hidden below the surface is a minefield that could sink his business for good, and at R&R, a sudden fog rolls in and traps a pilot in zero visibility.
