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? 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.
