"Palpitation Effect" is a thriller film produced in Russia in 2020, directed by director Andrey Zagidullin, starring Mariya Akhmetzyanova and Oleg An. The film tells the story of track and field champion runner Sergey, who lost his girlfriend after a stalled car accident, and was involved in a series of bizarre murders and became a suspect. In order to clear his charges, he cooperated with the policewoman Nasia, using Sergey's ability to travel back in time after making his heartbeat exceed the limit through intense running, and gradually delved into the truth, uncovering another real murderer hidden behind it.

The film opens with Sergey, an outstanding track and field athlete, whose life seems to be at the peak of his life, with a promising future and a fulfilling love life. However, a sudden car accident destroyed his world, and he lost his beloved girlfriend. Since then, Sergey has indulged in self-enclosure and self-blame, isolating himself from the outside world.

However, people around him have suffered strange deaths one after another, and all the evidence seems to point to Sergey. Policewoman Naxia took over the serial murder case and began to investigate, but soon discovered that things were not simple. During her contact with Sergey, she noticed his unique ability: when his heartbeat exceeded the limit through strenuous running, he was able to travel back in time for a short time.

Nasia and Sergey began to believe that this supernatural ability might be the key to solving the mystery. The two decided to use this ability to investigate the truth together. As time goes back, they uncover the secret hidden behind it. It turned out that all this was to cover up the real culprit, who turned out to be Sergey's most trusted friend.

Sergey's ability to travel through time makes the film full of suspense and surprises. Every time he went back to the past, he was trying to prevent the tragedy from happening, but things backfired. Every change seemed to trigger a new chain reaction, making the development of the story even more confusing. The tense and exciting atmosphere throughout the film makes it difficult for the audience to predict what will happen next.

Through the setting of time travel, the film explores the inner struggle and growth of the protagonist in depth. Every time Sergey goes back to the past, he not only has to face the complexity of the case itself, but also faces the pain and anxiety in his own heart. This kind of psychological description makes the film not only an ordinary suspense film, but also a work with emotional resonance.

The Palpitation Effect is a tight, thought-provoking thriller. Through the fascinating plot and impressive character creation, the film successfully combines time travel with suspenseful plots, bringing a visual and psychological shock to the audience. While exploring human nature, the film also tells us that when we try to escape our past, we often fall into deeper troubles.
