it's a brotherhood. coming up, a boat stuck in the ice in the bering sea. >> when we heard them say survival suits on, that keyed us to say this is not a salvage anymore, boys, we better be ready for a rescue. >> when "caught on camera: extreme rescues" continues. (woman) the constipation and belly pain feel like a knot. how can i ease this pain? (man) when i can't go, it's like bricks piling up. i wish i could find some relief.
