O’Dessa is set in a post-apocalyptic future and centers on the titular character (Sink) venturing from her family’s farm on a quest to track down a missing heirloom. Along the way, O’Dessa finds herself in a strange city, where she falls in love and must later use the power of song to save her beau’s soul.

Sadie Sink leads Hulu and Searchlight's 'O'Dessa,' an original, post-apocalyptic rock opera musical starring Murray Bartlett and Kelvin Harrison Jr.

Sadie Sink saved her character from the Upside Down using one (completely omnipresent) Kate Bush song. Now, she’s playing a new character who enters the underworld armed only with an acoustic and 16 original songs of her own.
