I watched this show, really, I did. I can’t remember a dang thing about it. This is what Wikipedia has to say:
The series centers on Prairie Johnson, an adopted young woman who resurfaces after having been missing for seven years. Upon her return, Johnson calls herself “The OA”, exhibits scars on her back, and can see, despite having been blind when she disappeared. The OA refuses to tell the FBI and her adoptive parents where she has been and how her eyesight was restored, and instead quickly assembles a team of five locals (four high school students and a teacher) to whom she reveals that information, also explaining her life story. Finally, she asks for their help to save the other missing people who she claims she can rescue by opening a portal to another dimension.
Alrighty, then.
