Cast members of the Theater Department at College of DuPage present “Ocean 9-1-1: Big Blue Rescue,” a mystery that takes place in the town of Oceanside. When a phone line goes dead during a desperate call for help, the Beach Bum Investigative Team must jump into action. Everyone becomes a detective to help the team follow the clues and solve the ocean mystery before it’s too late. Directed by Amber Mitchell, the play is entertaining for all ages.

No tickets are needed for the performance, to be held outside Cantigny’s First Division Museum. Seating is on the lawn, so blankets or chairs are recommended. Picnics are welcome, and food and drink concessions will be available.
