In the episode, Bender becomes a firefighter, and ends up housing a solar flare who wants to blow up the Earth from the inside.
Prompted by Morbo, who is covering the breaking story on location, Bender goes on to rescue all of the remaining victims.
After some time as successful firefighters, the other crew members notice that Bender was present just before every one of the fires they extinguished.
The flame introduces himself to Bender as a "being of pure solar energy", a member of a race that inhabits the Sun's photo-sphere.
Billions of years ago, the creature was imprisoned for treason, but Bender had unwittingly transported him to Earth.
When he announces his plans to ignite the Earth and rule over it, Bender realizes that this creature is the source of the fires for which he has been blamed.
To prevent this, Bender captures the creature, whom he begins to refer to as "Flamo", within his compartment of mystery and flees to an ice floe in the Arctic Ocean, where there is nothing flammable.
Fleeing with a reluctant Fry in hand, Bender falls through the weakening floor, ending up in the sub-basement near the lava pit.
