ZOOM, a PBS kids' show produced in Boston by WGBH, gets cancelled no thanks to PBS funding cuts. With this, the ZOOMers, the show's cast of kids, have to break up and go their separate ways. However, when two ZOOMers are presented with a horrifying video from a troll they befriended in a small door, they, along with a former ZOOMer and her new friend, have to find the ZOOMers and get them together before it's too late!
