A man in a blue tee-shirt, wearing a cap, is riding a white horse down a dirt road, in a rural setting of grass and hills.
The man is on his way to find a lost foal in his father's field
The man could be doing anything, not necessarily looking for a lost foal.  The field is not necessarily his father's field.
