Craig Lebeau and his team are pushed to the breaking point after a serious accident with a fully loaded logging truck traps their lead driver. With mud on the mountain– the worst it has been in years – the accident forces everyone to re-examine whether having the most dangerous job in Canada is worth it.

When Craig's little brother Brent cuts corners to get extra wood off the mountain, a mistake shuts the entire operation down; with the business hanging in the balance, Craig needs to decide if he can bail Brent out.

Craig's newest driver must prove himself on Mud Mountain; facing ice, muck and massive pressure, Theron tries to stay ahead of the fleet, only to be stopped by someone else's mistake.
