Panic ensues when a museum exhibit is stolen and K-9, Starkey, Darius and Jorjie are on the trail of the culprit, only to find a giant menace hiding in London’s abandoned sewers. However, is the alien really a threat, or is Drake the bigger evil? Starkey and K-9 face annihilation as they try to rescue the alien’s hatchlings before a gas bomb destroys them all!
