Here's a synopsis for Dead in 3 Days from the website of production company Allegro Film Produktions GesmbH: "'In 3 days... you're dead.' At first, Nina Wagner - a high school senior - and her clique think this SMS [mobile phone text message] is just a bad joke. But then Nina's boyfriend Martin is cruelly drowned in a lake. Soon after that the killer strikes again ferociously. The village is paralysed with dread. Panic rules among the members of the clique. They're all on the murderer's list. But why? Nina is the only one who discovers a mysterious trace leading to the brutal stranger's identity. No one wants to believe her. But time is running short...."
