All Of A Sudden (2016)

Embedded with suspense and thrill, this multi-layered mystery follows the fluctuating fortunes in the life of Karsten , a quiet mild-mannered man in his late thirties who ends up home alone with a pretty girl, Anna (Natalia Belitski), after all the other attendees of his house party have left. He assumes she’s a friend of a friend, she looks lonely and possibly even suicidal, and they end up at least kissing.

However, something drastic happens and Karsten ends up running to a nearby clinic that turns out to be closed at night not much later before running back home and calling an ambulance. Not much later, he’s interrogated by the police, who wonder why he didn’t call the ambulance right away, which perhaps could have saved her life.

As the police investigation into the death continues, the main questions that emerge are, what is the true identity of the mysterious woman who died at Karsten's home; what exactly happened between her and Karsten that night; did Karsten kill her? In the meantime, how will Karsten's life unfold?
