What details in "The Invisible Guest" make people think carefully and fear?

The Invisible Guest is a famous suspense movie for 17 years. This drama is famous for its brain-burning, and its plot is full of twists and turns, which makes people who watch movies surprised that every time they think they have guessed the plot, they will suddenly turn around, which makes us think that the facts are actually not the facts. This is a stage composed of many kinds of lies, which is unfolded by a carefully arranged murder case in a secret room, and lies are exposed one after another to promote the progress of the plot. The director interspersed one after another with interpolation and flashback techniques in this film, which made the story even more confusing.

The plot that scares me most is that the old woman in the play probably exchanged information about this serial case with her lawyer before meeting the male host. It is because the old woman knows that there are witnesses that she will make it clear to the man that the person who killed her daughter at the crime scene before witnessing the man is on his way to the court. Although the old woman didn't contact the witness, she forced the man to tell the truth by her own means.

So I think the old woman knows very well that there are witnesses, otherwise she wouldn't be so sure to tell the man that there are witnesses. The high IQ of the old woman is really admirable, after the man was arrested and boarded the plane. She had a premonition that the man might transfer the crime of killing his daughter to her husband and took measures in advance. He took out the synthetic poster when the man was arrested and deliberately covered the mirror. I figured out the truth version that the man wanted, which also scared the man.

I think the drama "The Invisible Guest" makes people unable to stop once they start, and the whole process comes out in layers of high energy. Friends who haven't seen it can try to watch it, and they won't regret it.
