Written by Malachi Smyth, it is set in the future on a war-ravaged Earth where four soldiers man Sentinel -- a remote military base in a vast ocean that separates two warring continents. While they await their relief or the enemy, the simmering tension amongst them escalates when a mysterious boat drifts into range.
