Zoe Saldana, Julianne Moore and Sia are one powerful trio.

Moore starts the video off by narrating a story about Saldana’s character, who is expecting a child and learns of an HIV diagnosis. Moore preaches that “if left untreated, it will be passed on to the baby growing inside her.”

Sia worked with her seasoned choreographer Ryan Heffington, who previously worked together on “Chandelier”, “Cheap Thrill”, “The Greatest”, on the powerful interpretive dance for the project.
