In Fabric (2018)

Spoiler warning - we summarise the entire plot of each film we choose.

Our stopping point is at 01:07:55 as we see a group of people doing a weird dance.

“In Fabric” is an art-house horror-comedy film written and directed by Peter Strickland.

Killer outfit. Eerie prediction.
Brainwashingmachine. 

Try it on.
