Olivia's stomach starts giving her problems a couple of months before an international trip. But the antibiotics she is given do nothing except give her more pain. Months later, while studying in France, Olivia is admitted to a hospital where she battles not only her continued pain but also doctors who don't speak English. Stu's dramatic weight loss has doctors giving him a diagnosis of acid reflux, but the treatments don't help at all and actually make things worse. The real diagnosis, however, leaves Stu in a state of shock at what doctors uncover.
