Castle Bravo
It's 1954¸ and you're a sailor or scientist aboard the USS Bairoko¸ an 'escort carrier' detailed to support secret nuclear bomb tests in the Marshall Islands. The bomb goes off in the Bikini atoll¸ the ship gets a light dusting of radioactive fallout¸ and now the crew is acting crazy¸ distress calls are coming in from monitoring stations around the blast site¸ and strange blips are showing up on the radar screens. What do you do?
