s07e20 Port Chicago

In 1944, in the midst of World War II, a disastrous explosion rocked the U.S. Navy's Port Chicago near San Francisco, killing more than 350 sailors, most of them African-Americans. Following the blast, a group of 50 sailors refused to return to work until changes were made to assure their safety. They were charged with mutiny and court martialed, but later their convictions were reversed. Now, a surviving sailor wants his record and those of all the other "mutineers" cleared. Asked to handle the investigation discreetly, Cmdr. Turner discovers that an injustice was done and goes head-to-head with Lt. Singer in the courtroom. Meanwhile, Harm goes house shopping with Lt. Sims.
