The Reluctant Vampire (S03E05)

A vampire takes on the role of a night security guard at a blood donation center. When supplies dwindle, he resorts to more traditional methods of obtaining blood. One night, the owner discovers his secret and attempts to blackmail him. However, just in time, the vampire's alluring assistant bursts in, sending the owner crashing into the vampire’s coffin. Meanwhile, a group of vampire hunters mistakenly identify the owner as the creature of the night, leading to a rather unfortunate encounter with a stake.
