A new, deadlier Venus probe is tested in a desolate area as a demonstration for Steve and Oscar, but a threat to Oscar to either hand over nuclear weaponry or see the probe set loose on the public forces Steve to find a way to stop the probe, even though it outmatches him in many ways.

When all physical assaults fail against the new Venus probe, Steve succeeds in tricking it into falling into a pit. However, when it starts drilling towards a city, Steve has a bigger problem than before.
