Pretty Guardian Sailor Moon Eternal The Movie Part 1

The first film in a duology adapting the Bishoujo Senshi Sailor Moon "Dream" arc.

The Dead Moon Circus has arrived in Juban with the hopes of liberating their queen, Nehellenia, by stealing the Legendary Silver Crystal for themselves. Using "Lemures," the Circus begins to convert people's dreams into nightmares in order to collect enough energy to plunge the Earth into darkness and turn it into a planet of death. In order to stop the Circus in their tracks, Usagi Tsukino and her friends must reprise their roles as the Inner Sailor Guardians.

When Mamoru Chiba suddenly falls ill after the appearance of a total solar eclipse, Usagi and Chibiusa encounter a pegasus by the name of Helios who is desperate to unseal the Golden Crystal, which Helios claims is the only way to save their world from the impending threat. Meanwhile, the Sailor Guardians discover that they can no longer transform following the eclipse and begin to fall victim to the Circus' Lemures. Will they be able to recover their powers in time to stop the darkness from taking over?
