Decoding Annie Parker

Loosely based on a true story, Decoding Annie Parker follows one family’s history of breast cancer — and the woman who teamed up with scientists to find out if the disease has a genetic link. The film, directed by Steven Bernstein, stars Samantha Morton as Annie Parker and Helen Hunt as the lead researcher on her case.

And in an exclusive clip from the film, we are taken back to 1974, when a food fight goes horribly wrong after Annie’s sister Joan (played by Marley Shelton) admits she’s found a lump in her breast.

Watch the clip below:

Decoding Annie Parker hits theaters and VOD on May 2.
