Uma Plots Her Revenge Against Mal in 'Descendants 3' Teaser - Watch Now!

Uma lets out a villainous cackle in the brand new teaser for Descendants 3.

In the new visual, Uma (China Anne McClain) explains just how Mal and the other VKs let the Isle of the Lost residents down and her own plan to get revenge.

The upcoming film follows Mal, Evie, Carlos and Jay as they return to the Isle to recruit a new batch of villainous offspring to join them at Auradon Prep.

When a barrier breach jeopardizes the safety of Auradon during their departure off the Isle, Mal resolves to permanently close the barrier, fearing that nemeses Uma and Hades will wreak vengeance on the kingdom.

Descendants 3 is set to premiere in August on Disney Channel.
