The Girls Next

Crystal and the Twins, Karissa and Kristina, are introduced as Hef's new girlfriends. Then, the Twins venture to Vegas to promote their issue of Playboy (they are Miss July and Miss August in the magazine's first double issue ever) and have a blast hanging out with Holly Madison.

Hef, Crystal and the Twins are in Vegas, where the Twins are promoting their issue of Playboy. After Hef and the Girls have a friendly dinner with Holly Madison in the Hugh Hefner Sky Villa at the Palms, Hef, Crystal and a few others go see Holly's performance in Peepshow.

After Hef shows Crystal and the Twins a video of a sexy, celebrity-studded, roller-disco party he hosted at the Mansion in 1979, the Girls are inspired to throw their own 70'sthemed bash on skates. To help them capture the era's authentic style and flare, they enlist the help of Hef's former flame, Barbi Benton, an outrageous rollerskating teacher, and plenty of beautiful Playmate pals.

Crystal and the Twins put on disguises and go on a Hollywood tour where they try to "break into" the Mansion. After they find the place secure, the Girls decide it is time for a camping trip in the backyard with their Playmate pals for the ultimate bonding experience. They'll tell ghost stories, have scary run-ins with nature, and even convince Hef to try a s'more for the first time ever!

As Hef's girlfriends, the Girls have unique opportunities to experience glamour and excitement. After living at the Mansion and looking through pictures of Playmates, Crystal decides she too wants to be one. Meanwhile, the Twins are cast in a Sofia Coppola movie as dancers. In order to prep for their roles, they take a pole dancing class and work with a choreographer to perfect a 6 minute routine.

Hef is invited to be the Guest of Honor at the San Remo Music Festival in Italy, and he takes Crystal and the Twins along for a romantic getaway. While there, the group takes a side trip to meet the Twins' Italian cousins in Roccaraso, where everyone enjoys an elaborate meal together. To wrap up the trip, Dasha, Playboy's 55th Anniversary Playmate, joins Hef and the Girls for the festival fun.

Hef's former girlfriend, Bridget, will emcee a fashion show to benefit an animal charity, and she has asked the Girls to model. After working with Bridget on the fashion show, Crystal and the Twins are inspired to do their own charity fundraiser. They decide to do something that has never been done before: host a lemonade stand in Holmby Hills outside the Playboy Mansion.

Hef, Crystal, the Twins, and their Playmate pals shoot a commercial for Guitar Hero at the Mansion. Later on, Crystal finds out a shocking family secret that inspires her to record a song her father wrote many years ago. With the encouragement of Hef and the Twins, Crystal records the song with pointers from music legend Smokey Robinson and surprises her mom with the emotional song.

Bridget recruits Crystal, the Twins, and Holly to help her throw Hef's former girlfriend, Kendra, the perfect baby shower. The Girls are on balloon duty, Bridget is in charge of the party theme, and Holly helps set everything up. After the festivities, Kendra heads to the Mansion where Hef invites her to join him at the Wishing Well so they can make a wish for her new baby boy.

Hef, Crystal, and the Twins celebrate their one-year anniversary, and the Girls make Hef the perfect gift to commemorate the special occasion – a scrapbook! After the scrapbook is complete, Hef and the Girls go out for the Twins' birthday. When the party comes to an end, Hef, Crystal, Karissa, and Kristina crawl into Hef's bed and present each other with anniversary gifts.
