In 1939, Captain Daniel McCormick is a United States Army Air Corps test pilot. After a successful run and subsequent crash landing in a prototype North American B-25 Mitchell bomber at Alexander Field in Northern California, McCormick is greeted by his longtime friend, Harry Finley, who is a scientist. Finley confides that his latest experiment, "Project B", has succeeded in doing the impossible. The machine, built by Finley and his team of scientists, is a prototype chamber for cryonic freezing. When McCormick's girlfriend, Helen, goes into a coma from an accident and the doctors doubt she will ever recover, McCormick insists he be put in suspended animation for one year, starting November 26, 1939, so he will not have to watch Helen die.
