Mel is worried about Niko's safety, so Mel and Harry come up with a plan to protect her, but Mel will need her sisters' help. Maggie notices that Macy is upset about her situation with Galvin, so she offers to do some recon with her, but they discover that things might not be exactly what they seem. Meanwhile, Maggie's sorority sister Lucy turns to her for some help, but Maggie struggles with telling her the truth because it could jeopardize her sorority future.
Three months after their mother is killed by an unknown demonic force, sisters Mel and Maggie discover that they have an older half-sister, Macy. The first time the sisters are under the same roof, they unexpectedly start exhibiting new magical abilities; the eldest Macy receives the power of telekinesis, middle sister Mel can freeze time, and the youngest Maggie can hear people's thoughts.
Soon after, Harry Greenwood gathers all three sisters together and reveals to them that they are witches, as was their mother. Marisol had bound her daughters' powers when they were born so they could live normal lives, and was in the process of unbinding those powers on the night she was murdered.
The sisters ultimately accept their new destiny as The Charmed Ones, the most powerful trio of witches who protect innocents and vanquish supernatural demons.
