In this documentary series, there will be a variety of patients with these mysterious cases. These patients try to find a diagnosis, and possibly a cure, for their mysterious diseases. The series reveals the methods followed by doctors, starting with social media and fixed medical experiences. In the end, each situation seems to be intertwined with new visions.
The series wisely stays in the realm of patients without short life expectancies, so weeks or months of research are possible. It also means no overtly tragic endings, even if all aren't perfectly happy.
The Netflix series definitely appeals to the logical, scientific parts of the brain, but it also goes straight for the heartstrings. It is an uplifting show, though not in the ways you might think.
Where the series really shines is in expanding the vision beyond mystery and into explorations of how being sick, particularly without much hope for any effective treatment, affects people's lives.
