The story is very similar, when midnight arrives the protagonist finds herself back at school (in a dream). She's not the only person there. Her childhood friend, Takahiro, and four of her classmates are there, they find themselves in a loop and try to find a way out.
There is also a brief romance between the protagonists, the only thing different about the series is that it is a horror genre.

La película es una adaptación de esta serie, sigo prefiriendo la serie, pero la película no esta mal :)
