The year was 1880. The place was Ocean City, MD. Mary (left) and Martha (right) are sitting on the beach, a couple hundred feet away from the boardwalk. Their third friend, Agnes has fallen out of her chair. Now covered in sand, she decided to wash off in the waves.All three ladies met at a church revival, which is why Martha has a bible on her lap.
Martha looks over to Mary and says "I think Agnes believes us". Mary and Martha are actually spies trying to capture Agnes. Mary responds to Martha and says "Everything is set at the restaurant". The ladies are going to get crabs at a nearby restaurant for lunch when they leave the beach. That is where Agnes is supposed to be arrested.
When its time to leave for lunch, Mary and Martha can't find Agnes. They think she found out about their plan and escaped. Mary looks out to the water and sees Agnes waving goodbye to them on a speedboat... That was the last time they saw her.
