Just to clarify, this quest is only available if you get the ending where you spawn in the White Orchard inn and are supposed to go on a hunt. It is not available in the other two endings. It occurs after you exit the tavern where Dandelion and Zoltan are talking. You'll see a soldier being bucked off his horse, you can't miss it.
