Two Jehovah’s Witnesses, Carol and her new colleague Leanne, hit the streets to spread the word of their religion as they go door to door in an average suburban neighbourhood.

Descending upon ‘lucky’ house number 7 (created in 7 days perhaps?) the two women begin their attempts to show the inhabitant “the light” and are quickly welcomed inside. The dishevelled owner is kind enough, but the ramshackle front room harks to anything but charitable intentions.

A very troubling comment whilst Leanne is excused to the bathroom adds an even more menacing tone to the proceedings. Yet questions are raised as to everyone’s true intentions when Leanne is on her mobile phone still upstairs in the house.

A church organ and choir on the score keeps a religious air to the proceedings and the stark lighting choices create extreme dark shadows and silhouettes, which are both visually interesting and keeps us mostly in the dark as to where we are heading.

Confined to the house and its small rooms, the shot choices help the audience feel a sense of coffin-like claustrophobia when the drama turns suddenly to horror. Writer JJ Smith does well by setting up the beginning with predictable pieces, but the short turns our preconceptions on their head and is all the more entertaining because of it.

Not wanting to spoil the end, the change in narrative focus leaves plenty of blood and a smidgen of holy retribution. Is an evil trinity finally defeated? Well, we’d highly recommend giving Number Three a watch if you’re a fan of lurid horror.

From suburbia to slayer, the film delivers pleasing twists and turns in its 7-minute runtime. And whilst the resident says the truth path to salvation is through suffering, the only thing you’ll be suffering is chills up your spine in this nightmarish but satisfying visit to a true house of horrors.
