Don’t be fooled by that angelic smile. Trine Dyrholm is ready to wreak havoc in “The Guest.”

In Mads Mengel’s drama – premiering at Karlovy Vary Film Festival – new father Karl (Simon Bennebjerg) is preparing for his child’s christening. Everything goes according to plan – until Karl finds out his mother, Vibeke (Dyrholm), will be attending as well.

Sold by LevelK, it’s produced by Monolit Film.

“When she arrives, you wonder: ‘Why didn’t he invite her?!’ She’s good company and doesn’t give a fuck about what other people think,” Trine Dyrholm tells Variety.

But there’s more to Vibeke, and her children are bracing themselves for the worst.
