Film Idea two James Swann

My film idea is a man waking up in the middle of no where and him searching from where he has come from. The man wakes up in the middle of a field lost and wondering how he got into that position. The man then walks on over the land until he finds a jacket that gives him a flash back to why he was in the field. The man then remembers that he was searching for something lost. He then is reminded of seeing a river. So he searches for a river nearby to where he woke up. The man then sees a young boy and remembers that he was searching for his son, who had run away. His son tells him of how he fell over and banged his head while chasing him through the field. The son then tells his father that he run away because of the amount of stress on him. The child then says to his father that he is sorry for running away and that he will return home with his dad.
