Meet Rachel Walsh. She's been living it up in New York City, spending her nights talking her way into glamorous parties before heading home in the early hours to her hot boyfriend Luke. But her sensible older sister showing up and sending her off to actual rehab wasn't quite part of her plan. She's only agreed to her incarceration because she's heard that rehab is wall-to-wall jacuzzis, gymnasiums and rock stars going cold turkey - plus it's about time she had a holiday.
