It is 2019. Something unbelievable has happend, for which 12 billion people have waited for a long time. The first contat with extraterrestrial life! But the aliens were not friendly and conquered the earth bit by bit. The special thing was that they did not come from space, but from the seas. They are aliens, that live in the water and came here by an artifically created Einstein-Rosen Bridge. Through this wormhole came not only the aliens, but also strange alien sea animals and they now render the coasts uncertain. Unfortunately, the world government found no experienced submarine pilot, to pit himself against the water aliens. Only a retired submarine veteran with an alcohol problem could be persuaded for this mission...
