Stalked After A One Night Stand

Rick and Tina have been flirting and making sexually suggestive remarks to each other at the office for months. They have let the sexual tension between them build up gradually over several months. During a Christmas party at the office, Rick invites Tina into his office, where they finally get totally intimate with each other.
While Rick considers what they had as a one-night stand, Tina on the other hand, is of a completely different opinion. She starts stalking Rick when he spurns her demands for more intimate encounters. How will it all end?
