Jo, a female journalism student, shows up one night in Jules's small underground laboratory on a university campus, having answered an online ad for a hookup that promises "sex to change the course of the world." Jules, a marine biologist, means this promise literally. During his research on a deserted tropical island, Jules discovered patterns among the behavior of fish that seemed to portend a premature end to most forms of earthly life. So Jules has turned his tiny lab-cum-apartment into a place to wait out the disaster and begin remaking humanity. An epic and intimate comedy that spans over billions of years, Boom explores the influences of fate versus randomness in the course of one's life, and life as we know it on the planet.
