Everything Has its Beginning

A secret military satellite detects a group of asteroids on a collision course with the earth which are behaving very suspiciously. It turns out that the only way to examine this phenomenon thoroughly is to send someone who can take a look at it from up close. This challenge is taken by the intrepid John Rider, a.k.a. the Space Captain.

The whole mission is handled by a special military and science team consisting of the Professor and the Colonel. At the very beginning it appears that this scientific mission turns into an emergency, as this astral cloud turns out to be a camouflage for a seemingly endless formation of spaceships... After taking on the first wave of unidentified objects, the Captain notices that the remnants of the enemy ships have fled in the direction of the Moon. The place turns out to be a forward military base of the alien forces. After destroying it, the Space Captain returns to the earth because he must stop the invasion, which is already underway...
