LEGO DC Super Hero Girls: Brain Drain (2017) on Netflix

Plot summary

Wonder Woman, Supergirl and Batgirl have to face an unknown villain, and short-term amnesia has hit them too. The three of them believed they had all had the same bizarre dream, in which they watched Katana and Bumblebee steal diamonds and gave chase before waking. The events were not only in their heads, and the girls come to understand that a full day is gone. Their classmates remember those missing hours, and the three of them acted extremely out of character: an embarrassing video of Harley Quinn appeared without her permission, and the school's Amethyst was switched for Principal Waller's car. Those acts get them expelled, and the girls set out to retrace the lost day and find out who took their memories.
