The German feature Sebastian Fitzeks Der Heimweg (The Calendar Killer) will drop on Prime Video on January 16, 2025, in 240 territories. An adaptation of Sebastian Fitzek’s novel, titled Walk Me Home, the film stars Luise Heyer, Friedrich Mücke, and Sabin Tambrea in key roles. The cast also includes Rainer Bock, Andreas Döhler, Romy Miesner, Shadi Eck, Isabel Thierauch, Dennenesch Zoudé, and Kristin Suckow, among others. Adolfo J Kolmerer directed the film from a Susanne Schneider screenplay.

The plot follows Jules (Tambrea), who works on an escort phone service that helps women reach home safely. One day, he gets a phone call from Klara (Heyer), a mother claiming that an infamous female killer will take her life that night unless she kills her own spouse (Mücke). Jules is Klara's lone shot at salvation, with the Calendar Killer breathing down on her neck.

“It’s too late. I’m going to be killed tonight,” says Klara to Jules in the trailer at the start of the call. Flashbacks show Klara in an unkempt room with the line: "06.12. Him or you. One will die."
