The Last Full Measure tells the true story of Vietnam War hero William H. Pitsenbarger (Jeremy Irvine), a U.S. Air Force Pararescuemen medic who personally saved over sixty men before making the ultimate sacrifice in the bloodiest battle of the war. Thirty-two years later, respected Pentagon staffer Scott Huffman (Sebastian Stan) on a career fast-track is tasked with investigating a Congressional Medal of Honor request for Pitsenbarger made by his best friend and PJ mission partner (William Hurt) and his parents (Christopher Plummer & Diane Ladd). Huffman seeks out the testimony of Army veterans who witnessed Pitsenbarger's extraordinary valor, including Takoda (Samuel L. Jackson), Burr (Peter Fonda) and Mott (Ed Harris). But as Huffman learns more about Pitsenbarger's courageous acts, he uncovers a high-level conspiracy behind the decades-long denial of the medal, prompting him to put his own career on the line to seek justice for the fallen airman.
