Veterans of "Alone" must use their skills, experience and 10 items to survive 50 brutal days along the frigid and windswept coast of Labrador, Canada.

The harsh Labrador environment proves too much for one participant to overcome; mistakes big and small haunt several participants, who must find new food sources.

The harsh Labrador environment has a profound effect on participants' mindset and strategies and proves too much for one participant to overcome.

Frost arrives and changes the landscape, creating new priorities for the participants; some deal with the consequences of a diet with no diversity, while others battle major shelter issues; the competition wears on the survivalists.

The landscape presents unique challenges and new opportunities as the participants try to maintain their weight; one participant's milestone celebration reminds them how far they have to go, while another tries to move forward after a major setback.

As the final three participants inch closer to the 50 day finish line, they're forced to adapt their strategies as they consider what their share of $500,000 is really worth to them. One survivalist comes face to face with a four legged foe, while another sets their sights on an overlooked source of meat. Heavy snow and frozen waters make the desolate wilderness even harder to tame.

Despite the deep freeze and cruel temperatures, the final two participants march onward; while small victories buoy their spirits, the survivalists struggle knowing that at any time the smallest mistake could send them home.
