Michael was short of money, but luckily he could count on his sister Monica's help. She was a famous model and was happy to help him. but she wanted a favour in return. She wanted to take a break from work and treat herself to a trip, but was tired of being annoyed by fans and paparazzi. Since a swap clinic had opened in the city, she in Michael's body would enjoy a holiday in complete anonymity, while he, as Monica, would be locked in her flat for a couple of weeks. He decided to accept, but after a day in his new home he realised he had made a mistake.
There are only high heeled shoes in the apartment and he often has to rest his aching feet, there is no wifi, just old fashion magazines to browse through to pass the time. Meals are delivered to his home every day, unfortunately only healthy food, no junk food. On the other hand, Monica has left him a rich collection of sexy toys, but the idea of pleasuring himself in his sister's body is disgusting to him. The only thing that makes him resist is the promise of a large sum of money. Before she left, she gave him just one piece of advice: «Stay hydrated, sis!» Michael can't help but think about all the alcohol he will drink once he is back in his body.
