The Hellmans, a family of devils, are sent by Satan to the surface of the Earth on a vital mission: Destroy a massive drill that will invade their underworld home.
The family decides to try out the country club, where Balthazor plays dog golf with his boss, Killbride. Tina puts a spell on the boss's wife, while Josh develops a crush and Mandy becomes a material girl.
Josh is upset because Balthazor hasn't been spending enough father/son time with him. Meanwhile, Killbride has a new initiative to collect dogs in exchange for guns for a secret project and a new British scientist is hired to work on the drill.
