World War II was underway when Desmond Doss (played by Andrew Garfield) decides to enlist. He’d grown up in an abusive family, with a father who’d served in WWI and suffered from PTSD. Desmond’s beliefs as a Seventh Day Advent wouldn’t allow him to touch or carry a weapon. As a Contentious Objector, Desmond stood firm in his beliefs in the face of harassment and persecution.
