The not-too-distant future. Several years ago, mankind launched a program to search for extraterrestrial life, Project Lima, led by Captain Clifford McBride. The last signal of the expedition was recorded in the area of Neptune, and since then nothing has been known about its fate. Captain McBride himself became a hero and the most famous astronaut, inspiring many to explore space.
Sixteen years after the disappearance of Project Lima, strange bursts of energy begin to occur on Earth, disabling electrical systems and wreaking havoc and destruction. According to the American space agency, the signal comes from Neptune, and now the son of a famous astronaut, Major Roy McBride, is assigned a responsible mission. He must get to the Martian base and from there try to contact his presumably living father.
