A SQUEAKY CLEAN FAMILY SWAP WITH A LOW-RIDER FAMILY, ON ABC'S "WIFE SWAP"

"Herrington/Trevino" - A clean-cut family who perform a wholesome variety show swap with a rule-free family of low-riders who let their girls wear and say anything they want, on "Wife Swap," FRIDAY, MAY 21 (8:00-9:00 p.m., ET) on the ABC Television Network. Each week two very contradictory families from across the country participate in a two-week-long challenge: The wives exchange husbands, children and lives (but not bedrooms) to discover daily life in another woman's shoes. This astonishing experiment repeatedly changes lives and redefines families.

The Herringtons can be found in any state on any highway in the U.S. as they travel, performing from one county fair to the next. Jim and Lory raise their four kids, Heidi (20), Joe (19), Gabe (14) and Miranda (12), on the road, living in the very tight quarters of an RV. The kids have agreed to live this lifestyle and to perform in the family's clean-cut stage show. Jim and Lory are extremely conservative and make sure the girls always look modest. Heidi says she has never been on an unsupervised date because her parents' strict rules have scared off all the boys. All four kids say they feel disconnected from dad Jim, as he spends most of his time off-stage by himself.

The Trevinos of Texas are all about low-riding cars and "keeping it real." Chris and Tera are laid-back parents who say this means raising their girls to be open and honest with them about everything. Their five girls, Myla (14), Farrah (13), Alana (11), Cameran (7) and Cris (5), all see their mom as their friend. Chris and Tera take their girls to car shows that feature other low-rider cars, scantily clad girls and flashy paint jobs. Chris is the lone provider for the family, and Tera spends most of her day "getting her beauty sleep" and hanging out.

In the first week, Tera is shocked that the entire family live in the small space of an RV. The family have a show to perform, but everything stops when Tera refuses Jim's request that she remove her lip piercing. Jim and Tera go back and forth on the matter and eventually Tera is allowed to perform as is. But she is embarrassed by the family's show and even more concerned that the kids are so sheltered, they have no idea what goes on in the real world. Lory arrives in Texas to find a house full of low-riders and car trophies. She quickly gets a low-rider makeover and attends a low-rider show dressed in a mini-skirt, low-cut top and pink hair extensions. She's concerned that the shows are an unhealthy environment for the girls. When she brings it up with Chris, they have their first of several blow-outs over Lory's criticism of their lifestyle.

In week two of the swap, when the wives change the rules and turn the tables, Tera is excited to teach the Herringtons to "keep it real." She's determined to show Jim how he's missing out by not spending more time with his great kids. The Herrington kids finally share their feelings with their dad about how he makes them feel, and Jim makes an admission of his own. Back in Texas, Lory tells the Trevinos that "low-riding is a raunchy lifestyle for hoochie-mamas, thugs and gangsters," and calls a tow-truck to take away the family cars. Lory also sets out to turn the Trevinos into a wholesome family act fit for the stage. After two weeks in another home, can Tera Trevino convince the Herrington family to give the kids some freedom and to really get to know each other before it's too late? And can Lory Herrington show the Trevino family that wholesome activities can also be fun?
