The Calendar Killer: Plot Summary

At the start of the movie, Klara Vernet (Luise Heyer) wakes up to a scary message telling her that within weeks, either she or her partner will die. This scary message came from the “Calendar Killer,” a notorious serial killer who terrorizes an area by telling his victims when they will die. Klara, a former lawyer, is trapped in a web of fear because both her abusive husband Martin and the police don’t care about her problems, leaving her alone and open to harm.

In the story, Jules (Sabin Tambrea), a man who runs a helpline called “Walk Me Home,” is introduced. Jules helps people who don’t feel safe walking home at night. He is always watching over his daughter, who sleeps in the next room, while he helps other people. One night, he gets a call from Klara, who tells him about a terrible thing that happened at a party her husband Martin threw where she was abused and given drugs. As she runs away from the party, she calls Jules for emotional support and starts to get close to him.

When Klara finds out that the Calendar Killer has sent her another message, her fears grow. Her need to stay alive and her feelings for her daughter Amelia are at odds with each other. While this is going on, Jules’s father calls to say that he is worried about him. People think that Jules’s father might be the killer because he is so obsessed with the Calendar Killer case.

When Martin forces Klara into his car after she tries to get away, things get worse. Martin’s abusive behavior is shown when he says that Klara is to blame for letting the abuse happen. In the end, Klara stuns him with a taser and runs to Amelia—who is being watched by a babysitter. What a shocking turn of events! Klara ends up in Jules’ apartment, where she finds out that he has been keeping a dark secret from her.

In the last scene of The Calendar Killer, Jules is revealed to be the title character’s serial killer. His reason comes from a terrible event in the past. Before she married Jules, Dajana, who is his wife, was abused. The horrible things that happened to her made her hopeless, and she tragically tried to kill herself by setting fire to their house. The fire killed Dajana and their children as well. This terrible loss threw Jules into a deep depression and turned him into a killer who goes after both abusers and their victims.

Jules’s crazy ideas become clear when he gives his victims a choice: they can kill their abusive partners or die themselves. He thinks that people who don’t do anything are too weak to live and could put their family in danger. His next target is Klara, and Jules makes her face her abusive husband Martin. In the final battle, Jules’s father steps in and kills his son to stop his reign of terror. At the end of the movie, Klara shows Martin’s abusive behavior, which leads to his downfall.

Is ‘The Calendar Killer’ Based on a True Story?

The Calendar Killer is a work of fiction, even though it has a gripping story and real-life themes. The movie is based on Sebastian Fitzek‘s 2020 German novel Der Heimweg (Walk Me Home), who is famous for writing psychological thrillers. Even though the story isn’t based on real events, it’s influenced by real-life events and themes, which makes it seem very likely.

A reader of one of Fitzek’s earlier books sent him an email in which she said she worked for a helpline service. This gave him the idea for Der Heimweg. This made Fitzek interested in helplines and how they help people who are having a hard time. He learned a lot about the subject and started to think of a story that would show how important these calls are to people’s minds. Fitzek also talked about a time when he pretended to be on the phone to get away from a dangerous situation. This made the idea of using phone calls as a plot device in the novel even stronger.

These things influenced the psychological depth and focus on domestic abuse in The Calendar Killer, but the story itself is made up. Fitzek is great at making complicated, multidimensional bad guys, like Jules, who has a sad past and isn’t sure what’s right or wrong.

Even though the Calendar Killer isn’t a real person, the movie’s themes of abuse in the home, trauma and moral dilemmas are all very real. The fact that Jules turned into a killer shows how terrible abuse is, not only for the victims but also for the people who love them. Klara’s journey from hopelessness to strength shows how strong you need to be to leave bad relationships behind.

The “Walk Me Home” helpline is a reminder of how important it is for people in need to have people who can help them. Even though it’s made up, it’s a lot like real services that try to keep people safe. It gives the story more realism that Fitzek chose to center it around a helpline like this.
