A job to die for.

Brace for the impact of another hard-riding season of IRT. Our danger-addicted truckers cant escape the pull of Alaskas Ice Roads where huge new monster loads and new ice routes over swift waters severely push the limits of success and survival. Hugh, Alex, Lisa and Jack return, competing with new rigs and new drivers - a potent mixture that tests their strengths and everything they know about trucking on the deadly ice roads. Season 4 features all 16 heart-pounding episodes plus driver biographies, behind the scenes insights, close calls and other previously unseen footage.
