After a chaos-filled summer, Kiko and Dom are ready to ease into a more laidback autumn and really put in some quality time together. Allowing Dom's ex roommate to crash with them, however, turns out to be a mistake when the guy won't leave. Dom struggles to cope as Travis dredges up things from his past he'd rather not remember and slowly casts doubts on his relationship with Kiko. Just when the tension seems to be too much, a murder after a Halloween party reignites the spark between Kiko and Dom. But when the body count begins to rise, it becomes clear that this is no ordinary killer. With few leads and no end to places the murderer could strike, this could either be a Halloween for Kiko and Dom to remember, or their very last.
