Blood In the Water

It's a cold, rainy morning on the research ship you're taking to the South Pole.

Your eyes are filled with sleep and you hear a faint rumble in the distance. You roll over from side to side, trying to fall back to sleep. A while later, you still can't sleep, and decide to get up and see what's happening.

Suddenly, a giant knock on your boat sends you tumbling down the stairs and you continue to hit your head on the side of the boat. Everything goes black as you go unconscious.
