Apostle is a 2018 gothic folk horror film written, directed and edited by Gareth Evans, and starring Dan Stevens, Lucy Boynton, Mark Lewis Jones, Bill Milner, Kristine Froseth, Paul Higgins and Michael Sheen.

In 1905, Thomas Richardson travels to a remote Welsh island to rescue his sister, Jennifer, who has been kidnapped and held for ransom by a mysterious cult.

Posing as a convert, Thomas encounters the leader, Malcolm Howe, who founded the cult with two other convicts, Frank and Quinn.

He forces Jeremy to admit that Jennifer was kidnapped for ransom, as the cult does not have the resources to pay for the continuous animal sacrifices needed to maintain the island's fertility.

Thomas flees from an old woman who chases him, and escapes to a beach cave covered in markings, depicting a deity.

Quinn reveals to a captive Jennifer and Andrea that he imprisoned The Goddess after he and Malcolm realized her powers and that he plans to repeatedly impregnate them and use their offspring as blood sacrifices.

The Goddess shows Thomas her history with the cult, and begs him to set her free; he grants her wish by unexpectedly immolating her.

The site's consensus reads, "Apostle resists easy scares in favor of a steady, slow-building descent into dread led by a commanding central performance from Dan Stevens.
