Survivors of an open seas accident must take on the challenges of a sub-arctic wilderness long enough to be rescued.

How does Cody attempt to improve their makeshift shelter?
CORRECT!
Cody uses the plastic tarp from the raft, along with the mylar blanket, to insulate the shelter. The heat from the fire passes through the plastic sheathing and is radiated back by the Mylar blanket to warm the shelter.
