Two old friends… Eddie is a retired Water and Power worker and Arnie is a retired teacher. Eddie has a joke for every occasion. Arnie has a factoid to drop into every conversation. Gracie is tired of Eddie’s jokes, and Norma has heard a hundred too many facts about too many things. The women suggest they can liven up their lives by seeing if the grass is truly greener in the other person’s house. They decide to switch partners; becoming swinging seniors…”sweniors.” Or do they?
