Laura and Susan have had a love/hate relationship since their schooldays. Laura presides hopefully over a large, unruly family as she approaches her silver wedding; Susan is exuberantly independent and a most spirited advocate of the single life. At their regular lunches they view each other with a mixture of deep affection and even deeper suspicion. But when the balance suddenly alters, the two friends are surprised to discover something new and potentially wonderful about ... life after lunch.
