When Melanie “Mel” Vera and her sister Maggie lose their mother in a horrifying accident it shatters their world and threatens their sibling bond. Then they get another huge shock: they have an older sister, brilliant geneticist Macy, whom their mother kept a secret all these years. With the emotions of the newly-reunited sisters running high, each of the girls suddenly exhibit impossible new abilities. But don’t worry, there’s a perfectly reasonable explanation to all of it…or so says Harry Greenwood when he gathers the three sisters together to reveal they’re actually powerful witches, as was their mother. It’s a lot to take in for the sisters, but they ultimately accept their new destiny as The Charmed Ones, and their new duty to protect humankind from the demons that walk among us.
