Jon is working on his school assignment. Jon tells his dad that the object is not a drone but a “flying saucer”. It flies away, Krypto reacts on command and bites on the object. Jon tells him to stop before it breaks. Then, unexpectedly, the three of them are transported to Dinosaur Island.

Clark realises that the device may be their only way back home. Therefore, they want to find it immediately. This may not be as simple as they thought, since there are dinosaurs on the lookout, hunting for their flesh.
