Rebecca Gomperts had a wild idea: To provide abortions at sea for women with no alternative. When her ship is faced with governmental, religious, and military blockade, she decides to use new technologies to train women to give themselves abortions using WHO-researched pills; creating an underground network of emboldened, informed activists who trust women to handle abortion. Vessel is the story of a woman who hears and answers a calling, and transforms an improbable idea into a global movement.
