Question: are there vampires in from dusk till dawn

Answer: Yes, The bar employees transform into vampires and most of the patrons are killed. Richie is bitten by a stripper, becomes a vampire himself, and dies after Seth drives a wooden stake through his heart. Only Seth, Jacob, Kate, Scott, a biker named Sex Machine, and Frost, a Vietnam veteran, survive. The others come back to life as vampires, including Richie, forcing Seth to kill him. Sex Machine is bitten, becomes a vampire, and bites Frost and Jacob. Frost throws Sex Machine through the door, allowing an army of vampires to enter as bats.
