The relationship between Tash (an intelligent but reserved science journalist) and Brett (a confident and somewhat egotistical television host) is in trouble. When they first met, it was love at first sight, but their inability to compromise is leading to a breakup. The situation gets worse, however, when the 'natural forces of the universe' get involved, and Brett and Tash wake up one morning to find themselves trapped in each other's body. Each learns valuable lessons as they both adjust to very different lives.
