In rural Virginia, Young and Pak Yoo run an experimental medical treatment device known as the Miracle Submarine—a pressurized oxygen chamber that patients enter for therapeutic “dives” with the hopes of curing issues like autism or infertility. But when the Miracle Submarine mysteriously explodes, killing two people, a dramatic murder trial upends the Yoos’ small community.
Who or what caused the explosion? Was it the mother of one of the patients, who claimed to be sick that day but was smoking down by the creek? Or was it Young and Pak themselves, hoping to cash in on a big insurance payment and send their daughter to college? The ensuing trial uncovers unimaginable secrets from that night—trysts in the woods, mysterious notes, child-abuse charges—as well as tense rivalries and alliances among a group of people driven to extraordinary degrees of desperation and sacrifice.
