Shannon Tweed hates surprises.  Gene Simmons loves them.  On his way out of town to attend the grand opening of the Hooters Hotel & Casino in Las Vegas, he asks Nick and Tracy Tweed (Shannon's sister) to plan a surprise birthday party for Shannon on his behalf.  While in Vegas, he gets roped into attending the wedding of a fan and his fiancée -- and even gives the bride away.  When Shannon inadvertently finds out that Gene was not only planning a surprise party for her AND that he attended someone else's wedding, she ups the ante and plans sweet revenge on her longtime boyfriend.

If your dad's Gene Simmons and you want to go into the music business, some career counseling is to be expected.  But when Nick starts a band of his own, Gene transforms from a proud father into an overbearing manager.  From the band's name, to the clothes Nick wears, Gene won't leave his son alone and he even prematurely books Nick's first gig.  Meanwhile Shannon sneaks 14 year-old Sophie into LA Fashion Week, and witnesses every hot stud at the event flirting with her little girl.

Gene is in the dumps because a security guard at a TV studio doesn't recognize him, while Shannon confesses to her sister Tracy that she's considering having another child. Gene's ego gets a boost when he learns that KISS will be honored in Las Vegas for a TV special, but he has to make a special deposit for Shannon before he can rock and roll all night and party every day.

Gene Simmons didn't start driving until he was 35 years old and Nick is studying to get his driver's license. An admittedly horrible driver himself, Gene faces off against Nick in a driving test challenge, with the threat of having to humiliate himself in the middle of Beverly Hills if he loses. As his daughter starts to date, a nervous Gene insists that Shannon take their daughter to a self-defense course. The driving test and the self-defense course both prove painful for Gene, who learns that father doesn't always know best.

Shannon notices Gene is losing the battle of the bulge, so she tricks him into attending a ritzy weight-loss spa. When they arrive, Gene learns that they have separate rooms, and his food intake is rationed. Gene wants two things - food and sex. Will the Demon get what he wants? Meanwhile, all hell breaks loose at home when crazy aunt Tracy baby-sits Nick and Sophie -- or is it the other way around?

It's Career Week for Sophie Tweed-Simmons and her assignment is to tag along with Gene to work. It's a familiar assignment, but if your dad's Gene Simmons, expect the unexpected. Shannon is not too pleased to discover that Gene has taken their 13 year-old daughter to auditions for a sexy new exercise video called Sexercise. Shannon turns up the heat on the Demon and has Sophie talk with her dad about the birds and the bees. Sophie's talk provokes the rock star who's slept with 4600 women to prove that Gene Simmons and safe sex can be part of the same sentence, as he takes his shot at a PSA for Planned Parenthood. No sooner than he finishes the PSA, he is challenged to wrestle a reject from the Sexercise auditions as she calls him a sexist pig. He accepts the challenge only to find out that when he gets to Miss Kitty's night club it's... lube wrestling.
