Louis Theroux travels to California, the birthplace of plastic surgery. In this land obsessed with beauty and self-image, just a few thousand dollars and the flick of a knife can turn people into whoever they want to be.

Louis meets Eve, who is set to perform a complete makeover on Laura. Following some initial advice about clothes, Laura’s ready for “the next level”: a boob job, brow lift and liposuction. Sensing a bully at work, Louis wonders who’s really in control of Laura’s decisions.

Louis also strips off to compare bodies with Kris, a 24-year-old DJ who’s forlorn – despite hours in the gym he cannot get the six-pack he desires. It’s hurting his reputation with the “beautiful people” so he resorts to lipo-sculpting – sucking out the fat between his stomach muscles.

Dr Linder is the “boob man” of Beverly Hills. Cruising Rodeo Drive with Louis, he points out all the breasts he’s enlarged. It appears he’s tweaked most of LA!
