In the city of Pompeii, the morning of the eruption, Jimmy and his son went to go on a walk at the beach but they leave their dog, Doodles, in their house as a punishment for digging up at floor of their house.
We're gonna die!
Jimmy and Max feel an earthquake and looked up at Mount Vesuvius. It looked like it was going to explode so Max ran back to save his dog. Jimmy had no choice but to follow.
Jimmy and Max arrived at their house and rushed in to find Doodles. While they're in their house, the front door collapsed, leaving them trapped in their house.
Woo hoo! We live!
They heard an explosion and realized that the volcano had just erupted. They were locked in their house and would slowly suffocate from the smoke or the lava would burn through their house.
Max looks at Doodles who is digging at the floor and tells his dad, who gets a shovel and helps Doodles dig a hole for all of them to fit through.
Jimmy, Max, and Doodles escape through the hole and run to the ocean where they find a rescue boat.
