Soon after arriving in Sparksville, Ben and his friends notice that something strange is happening. The townspeople are all acting very odd, and their behavior is becoming increasingly erratic with each passing day. The trio decides to investigate, and they soon discover that the cause of the strange behavior is the black liquid that the townspeople are drinking.

As the investigation continues, Ben and his friends learn that the water in Sparksville has been contaminated with an alien substance.
