Teenage Tom (Stef Aerts) and 30-year-old Xavier (Wouter Hendrickx) are strangers united by a common diagnosis -- both men have cystic fibrosis, a terminal condition of the respiratory system. After meeting during one of their grueling treatments, the two begin an unlikely friendship. Tom and Xavier find strength in each other as they wreak joyful havoc at the sterile hospital, where -- as their conditions deteriorate -- they are forced to spend more and more of their time.
