The end comes from beneath the water

Gary, his wife Emily and their daughter Vicki, live on a house boat. It means that he can work from home and still make enough money to look after his family. But keeping them safe becomes a lot harder when a storm brings monsters up from the water. Gary and his family try to hide, and then to run away, but in the end he has no choice but to fight. And if he doesn’t win, they are all as good as dead.
