Four Alarm Fire and Brimstone is the ninth episode of Rescue Heroes.
A neighborhood kid accidentally sets fire to Jake's former "little brother" Nick's house. Jake and the Rescue Heroes are called to assist local authorities. The house is damaged and will take time to repair, so Jake offers the Mountain Action Command Center as a temporary home to the family. When Nick stows away on the Hyperjet, he inadvertently causes serious complications during a rescue mission on an active volcano.
