Lenora has recently inherited her grandmother's house and farm land. While exploring the property, she loses track of time and is in the woods when darkness falls. She is astounded to find an occupied cabin in her woods, one that had not been there earlier. She soon learns the cabin only appears at night. In the daytime, only an old foundation remains. What is going on? Lenora waits for night and returns to the cabin in the woods. She is determined to find out why it is there only at night and who lives in it. She is caught looking in the windows of the cabin by an attractive man named Adrian who lives in the cabin with his mother. Lenora is stunned to eventually discover the man and his mother live in a different time; it is 1865 and Adrian is leaving soon to fight in the War Between the States. She is dismayed to realize she has fallen in love with a man who lived over 150 years ago. During the daylight hours when the cabin has disappeared, Lenora finds a small graveyard on her property. One of the stones belongs to Adrian, and he is going to die in just a few days in 1865. She has to find a way to change history so that Adrian will live. She is willing to give up everything to live with him in his time. But, a complication comes along by the name of Johnny. He is alive and is the spitting image of Adrian. How is she going to decide what to do? Should she go to the cabin under the moon to be with Adrian, or stay in her time to be with Johnny?
