Set in the near future, unchecked and rampant climate change has caused temperatures and sea levels to rise catastrophically. Surrounded by an endless ocean thousands of miles from home, a skeleton crew of soldiers (Bosworth, Kretschmann, Laviscount, and McCann) stand as the last bastion, defending their homeland from an invasion by an enemy they have never seen. Their tour of duty ended 3 months ago with no relief in sight. Alone and uncertain as to what fate awaits them, the simmering tension amongst the crew escalates when a mysterious boat drifts into range - is it the help they have been waiting for, or something far more sinister?
