At the wedding of Peter and Rita, an old man wanders in and asks if he can kiss the bride. As they look into each other’s eyes, they wonder what it would be like to be in the other’s place. One magical kiss later they find out, as their souls are exchanged. How they and their loved ones cope with this situation is the subject of Craig Lucus’s Prelude to a Kiss — a thoughtful and delightful story of commitment. Daniel Zisko directs.
