This is an action adventure movie in a sci-fi setting. When a space shuttle returns home, the crew does not know they are bringing aliens with them. During a repair mission, an astronaut’s suit is hit by a micro-meteor. He survives and manages to make it back to safety in the shuttle. He is fine until they reach Earth. He is put in the hospital in Houston. Overnight, he hatches a batch of moths that attack only people who have B negative blood. The people who are attacked become monsters. Two doctors only have 48 hours to cure them, or the world will be lost.
