Night Light, father of two foals, loving husband, and the hard-working stallion had recently discovered that his wife, Twilight Velvet, who he thought was the most faithfful woman he ever met, has been having a secret affair with another stallion while he was at work... for the last 5 years. All because he was exhausted from his tiring hours on the job to support his family.

Now, his anger was boiling, hot and venomous, flowing through his veins. Many thoughts began to pop into his mind...But one idea, in particular, caught on to him. His company's costume party, his ideal place to carry out his revenge.

But, what will take him by surprise is that he is not the only one who has a score to settle with Velvet.
