Optimus Prime builds a new team of young Cybertronians to train as first responders at the Rescue Bots Academy.

Hotshot learns to find his place on the Rescue Bot Recruits team with the help of the Mul-T-Cog and his friends.

Hot Shot is frustrated by their slow speed during a simulation and, while taking a shortcut, accidentally runs into Chuck. He must baby-sit the damaged RBA Test Robot until the new parts are ready, but Chuck won't stay put.

At his teammates' urging, Hoist invents some new `cool tools' to improve their rescue abilities. But they fail spectacularly, leaving Hoist feeling awful - until Boulder teaches him not to give up.

When the recruits get caught in a snow storm, Whirl's police bot attention to procedure and detail saves the day.

The recruits keep failing a fire rescue simulation, until they realise that on Earth even the tiniest living things play a huge part.
