In this movie, Poirot is taking a break and enjoying some time with his friends when a murder happens in the same building. The story mostly takes place inside the apartment building, especially in the small, mysterious third-floor flat. The small space and sounds from other floors make the story feel close and tense, as if there’s no way to escape. This tight setting makes every person seem like they could be the killer—especially when Poirot begins to get closer to the truth, and we can watch how each person reacts.
The story is told from Poirot’s view, so we see everything through his sharp eyes. He notices little things, like when someone says something small, shows a tiny change in expression, or when something in the room feels just a bit “off.” These details pull us into the mystery, making us feel like we’re right there with him, trying to solve it too. Poirot’s calm but curious way of solving the mystery adds a warm, even funny touch. It makes the story not just about the crime, but about understanding each person’s story and seeing things in a new way.
