The film premiered on Disney Channel on August 2, 2019, and in other territories worldwide starting on October 12, 2019.

Mal, Evie, Jay, and Carlos visit the Isle of the Lost to choose four new villain kids (VKs) to take to Auradon.

They pick Dizzy, granddaughter of Lady Tremaine; Celia, daughter of Dr. Facilier; and Squeaky and Squirmy, the twin sons of Mr. Smee.

As the older VKs return to Auradon, Hades attempts to break through the Isle's barrier, but Mal stops him.

Unable to let go of her resentment of Mal, Audrey steals the Queen's crown and Maleficent's scepter from the museum, gaining magical powers and becoming a villain.

Following the theft and Hades' escape attempt, Mal suggests the best way to protect Auradon is to close the Isle's barrier permanently.

When Mal admits her plan to seal off the Isle permanently, the group breaks apart and Celia, learning she can never see her father again, drops the ember in water.

Hades does so, but decries the double standard by which Audrey is immediately forgiven for her crimes as she is not considered a villain.

With Ben and Fairy Godmother's approval, Mal replaces the Isle's barrier with a bridge, and the people of the newly merged society celebrate.

In the end, Evie is with Doug, Carlos is with Jane, Mal and Ben are engaged, Jay and Gil plan to travel the world together, and Audrey seems to become romantically attached to Harry after Uma rejects him.

In a mid-credits scene, Mal, Evie, Jay, and Carlos race across the bridge to the Isle to reunite with their parents.

Additionally, Judith Maxie reprises her role as Queen Leah, Princess Audrey's grandmother, from the first Descendants film.
