A space capsule that landed on Earth 65,000,000 years ago has been unearthed by archaeologists. While Dr. Paradigm has taken interest in the space capsule, an incident involving the capsule's prisoner Bad Rap causes Mantaman to fall under his control (the alien whose DNA was used to create Mantaman was one of Bad Rap's many creations) as they plot to control the largest radio telescope in order to contact Bad Rap's fellow Raptors. Now the Street Sharks must work to free Mantaman before Bad Rap's transmission to his fellow Raptors gets through.
