Set in London in 2016, Fish follows seventeen-year-old Karya as she attempts to resolve the mystery of her brother's disappearance. When her mother's unconventional theory about his whereabouts begins to seem plausible, Karya enlists her best friend to test it through an elaborate online experiment, targeting the internet's more obscure and dangerous spaces. What starts as a search for answers escalates into something neither of them anticipated.

The play is a darkly comedic coming-of-age story that moves between sharp humor and genuine tension, using the framework of grief and girlhood to examine the consequences of games played without full knowledge of the stakes.
