According to VancouverFilm.Net, despite the upcoming third season of The CW's "Charmed" premiering January 24, 2021, shooting on the supernatural series has been locked down (again) due to an individual from the production testing positive for 'Covid-19':
"Mel is a graduate student in the women's studies department her mother heads at 'Hilltowne University'. Maggie is a freshman considering rushing a sorority and going 'on' again with her on-again off-again boyfriend 'Brian'.
"Macy is eager to connect with Mel and Maggie, but Mel can't handle another shock, and shuts her out. With the emotions of all three sisters running high, each of the girls suddenly exhibit impossible new abilities: Mel can freeze time, Maggie starts hearing others' thoughts, and Macy has telekinetic powers.
"But don't worry, there's a perfectly reasonable explanation. Or so says 'Harry Greenwood', the new chair of the women's studies department, when he gathers the three sisters together to reveal they’re actually powerful witches, as was their mother. And he's not really a professor, he’s their 'Whitelighter', a witch's advisor and guide.
"Not only that, but Mel was right: their mother’s death was no accident – she was murdered by unknown dark forces. It's a lot to take in, but ultimately the sisters accept their new destiny as 'The Charmed Ones' and their new duty to protect humankind from the 'demons' that killed their mother.
