In Nome, Alaska, miners risk their lives mining below the ice on the frozen Bering Sea for a fortune in gold.

In the fourth series of the hit show, ‘Under The Ice’ takes us deep into the lives of these extraordinary fisherman and their golden galleons.

"Mr. Gold" Shawn Pomrenke is back on the hunt for a payday with his megadredge ‘The Shamrock’.

Emily Riedel has her sights set on being the best, and as one veteran hits his biggest payday ever, another nearly loses his life. As the hard reality of the winter season begins to set in, partnerships become strained as tempers and egos flare.

The danger looms ominously over the crews at all times as threats of sinking, nitrogen poisoning, treacherous crew and turf war shatter close friendships, and all for the lure of gold.
