Credo, also known as The Devil's Curse, is a 2008 low-budget psychological horror film directed and produced by Toni Harman and written by Alex Wakeford.

It stars MyAnna Buring, Clayton Watson, and Nathalie Pownall, Rhea Bailey, and Mark Joseph as five British college students that find themselves trapped in an abandoned seminary with a demon.

It cuts to a radio recording of two men discussing the nature of evil while close-ups of insects and occult writings play.

After the librarian (Chris Courtenay) notes that she is always the last to leave, she packs up her belongings and heads home to find a loud, raucous party already in progress.

The party was a touch too rowdy and Alice, along with her four roommates Jock (Clayton Watson), Scott (Mark Joseph), Timmy (Nathalie Pownall), and Jazz (Rhea Bailey), find themselves evicted the next morning.

Time passes and the power goes out; Alice hears growling and sounds of something being dragged along wood and ventures to one of the rooms they're sleeping in to find the other four are using a shot glass on a Ouija board.

After Alice's father finishes his monologue, the film cuts back to Jock, Scott, Jazz, and Timmy on the Ouija board.

The results of the bat box experiments varied; in the fire station itself, Alex picked up a moaning sound on the top floor.

On another location they investigated but didn't film at, Toni felt the bat box definitely picked up the sounds of an entity responding to their questions.
