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.
It's a recipe for disaster when Mandy starts dating the boss' son, prompting an invitation to a Killbride barbecue for the entire Hellman clan.
Balthazor is assigned the task of pitching a Petromundo plan to build preschools on toxic marshlands.
Tina's parents, who have always hated Balthazor, come to see their daughter and her family in their new home.
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.
Balthazor is forced by his boss to test out a new weight-control device, a robot that insults its owner into diet submission.
Tina is responsible for showing the town to the wife of a Japanese businessman doing business with Balthazor's boss.
Balthazor's boss, Killbride, decides to unfreeze the head of Atilla the Hun to handle some personnel cuts.
Balthazor is recruited by a mysterious man who shares his desire to destroy the drill.
