Sundowners (2016)

Certain a city is under siege by a "creature of the night" the local Catholic Chapter has sent a squad of slayers to eradicate a centuries-old enemy, Vampire Violet, at the behest of the Vatican. Vampire Violet has set up shop in the suburban sanctity of Arkham, Massachusetts, and she's been slowly sucking her way through the entire town. Little does she know, however, she's about to come up against The God Squad's secret weapon - SUNDOWNERS pathogen, which has been hijacked from The God Squad's archenemy (and Violet's benefactor), pharmaceutical titan Cerberus Unlimited.
