Welcome to paradise! The series kicks off as you get to know Hef's three girlfriends, Holly, Bridget and Kendra, and how life works at the world's most famous Mansion. Who would want to leave this place?

When two aspiring Playmates arrive at the Mansion to stay the night before they shoot test pictorials, Hef's girls greet them with varying degrees of hospitality. Hef makes a surprise announcement to Holly, Bridget and Kendra.

When you're one of Hef's girls, your birthday party isn't just a quaint gathering, it's an event. Kendra's 20th is a two-day celebration, which starts off with a trip to the 2005 Playboy Jazz Festival with the gang and her gorgeous pal Destiny.

This week brings another birthday bash, but this one is for Playmate Carmella DeCesare. It's Vegas, baby and the girls help Sin City live up to its name.

Put up your dukes, it's Fight Night at the Mansion! There's a whole lotta action inside and outside of the the ring when Hef's former girlfriend, legendary Playboy cover girl Barbi Benton pays a visit.

The girls spend their Fourth of July preparing gift boxes for United States soldiers.

Take a picture. It'll last longer! That's exactly what happens on this episode when the girls fulfill lifelong dreams and pose for a sexy Playboy pictorial.

"Lingerie or less," that's the dress code for Playboy's Midsummer Night's Dream, the annual hedonistic ritual that has become one of L.A.'s most anticipated summer events. To prepare for the massive soiree, the girls endure a gauntlet of hair and makeup appointments, bikini waxes and tanning sessions.

There's plenty of hot stuff going on this week when the girls slip between the sheets for another sizzling photo shoot. Holly decides to renovate the guesthouse, and girls finally get to see themselves on the cover of the November issue of Playboy.

It's Halloween at the Playboy Mansion! While Holly and Kendra put their wits together to decorate tombstones, Bridget sets out on a full-scale ghost hunt and contacts a paranormal investigator to get to the bottom of the Mansion's long-running history of spirits.

It's road-trip time as the girls head to Bridget's hometown of Lodi, California. After hitting the road super early, they hang with Bridget's family and friends, and enter a grape-stomping competition.

The girls take a bite of the Big Apple when they travel to Manhattan with Hef as part of the promotional tour for Holly, Bridget and Kendra's November cover of Playboy. The group travels to the East Coast in style, but the good times are interrupted by nerves, as the girls are set to appear on The View.

Hef, Holly, Bridget and Kendra blow into the Windy City, Hef's birthplace and home of Playboy Enterprises, Inc., to continue promoting the November issue of Playboy. They take in a visit to Playboy HQ, dine at trendy eatery Japonais and more!

Whodunit? That's the big question at Bridget's murder-mystery-themed birthday party. But before the big celebration, Holly gets a smashing driving lesson in Hef's beloved 1959 Mercedes, and Kendra shows off her drive on the tennis court for a charity tennis tournament.

The girls return to Las Vegas, with Hef this time, for two very important occasions: to promote the new Playboy Club at the Palms Hotel & Casino and to preview designer Roberto Cavalli's sexy "bunny couture".
