Derrick & Sally: Bathtub Killers (2015)

Sometimes you go drinking. Sometimes you black out. And SOMETIMES you wake up two days later in bed with a 15-year-old girl named Sally. At least, that's what happened to Derrick Jansen. But don't tell him about the bodies in the Bathtub. Especially because he's the jackass that put them there. Besides, his day is already about to get a lot worse. It's Dexter meets Jekyll and Hyde, done in the style of Buffy.
