Ms. Wright gives an ominous introduction to the school's next big assignment, Radiant Week! But… what is Radiant Week? The first years have no idea, and nobody will tell them. Skyler is freaked out about this mysterious project, and the De'Vious Twins tell her a spooky story about a Radiant Week where a student had a meltdown and roamed the halls like a ghost, scaring all the first years. Good thing Skyler doesn't believe in ghost stories… until really creepy things start happening around school and Poppy goes missing! Is there a dark side to Rainbow High?
