HBO Films has released the official trailer for their upcoming telemovie, The Immortal Life of Henrietta Lacks. The feature length film, based on the critically-acclaimed book of the same title by author Rebecca Skloot, tells the true story of Henrietta Lacks, an African-American woman whose cells were taken for research without her knowledge while being treated for cervical cancer.

The film features Tony winner Renée Elise Goldsberry as Henrietta Lacks, Oprah Winfrey as Deborah Lacks and Rose Byrne as Rebecca Skloot.

Here’s the film’s synopsis:

Science took her cells. Her family reclaimed her story.

Told through the eyes of Henrietta Lacks’ daughter, Deborah Lacks, the film chronicles her search, along with journalist Rebecca Skloot, to learn about the mother she never knew and understand how the unauthorized harvesting of Lacks’ cancerous cells in 1951 led to unprecedented medical breakthroughs, changing countless lives and the face of medicine forever.

The film will premiere Saturday, April 22.
