Teens Zac and Mia are battling cancer in the same hospital. In the real world they would have very little in common, but in the hospital they develop an unbreakable bond. If cancer is the variable that changed everything, the only constant is their need for one another.
In Season 2, Zac is excited to get his old life back, while Mia wrestles with hopelessness about her uncertain future and condition. As a couple, they're now forced to navigate their budding relationship out in the real world, unprotected by the walls of the hospital.
