Swan Song is a singer that was asked to perform at a small charity event that her friend/crush Chatter Cherry organized.
Everything seems to go fine until the news of an old friend joining the Knights of Equestria reaches her and old hurtful memories Swan Song thought she buried resurface to haunt her.
When Swan Song was a foal she was just looking for a quiet place to practice her singing.
She believed to have found just that when she noticed a hole in the fence behind her parents house that lead to a peaceful forest clearing.
However, Swan Song didn't know that her singing would lure someone else towards it as well.
