This is loosely based on the myth of Tír na nÓg. The hero Oisin meets a mysterious woman Niamh of the Golden Hair, falls in love and returns with her to Tír na nÓg (land of the young). After a time he gets homesick and Niamh lets him return but warns he must remain on the horse he travels back to Ireland on. When home he learns that 300 years have passed and all those he knew are gone. He stops to aid some men moving a stone. While doing this he falls from the horse and instantly ages and dies. The horse returns to Tír na nÓg.
