Seventeen-year-old Parker is 3,300 feet under the sea in a high-tech submersible named Petunia, on a solo mission to find the fabled lost city of Atlantis. But as sonar pings echo and shadowy sea creatures pass by, reality filters through—the clanging of a high school bell. Back on dry land, Parker’s fiercely grounded sister Colleen must journey to face her own demons: from the halls of the high school to the depths of the ocean floor. Through shifting scenes that alternate between deep-sea fantasy and high school reality, we discover these siblings’ underwater quest is fueled by something far more personal than treasure: searching for a way forward after the loss of their mother threatens to unravel their family.

A theatrically rich, imaginative tale, this play is ideal for schools and companies seeking a contemporary, flexible, emotionally rich piece with vivid theatricality and a deep heart. This beautiful, refreshing sibling story becomes a genre-defying plunge into loss, memory, and navigating the line between drowning and surviving.
