Plot introduction
It turns out that some days ago, the newly married Shelby couple were attacked by a gangster. At the beginning of the film, we mistakenly thought that the murderer had brutally killed Leonardo's wife. Although Leonardo himself struggled back from death, he suffered from a strange "short-term memory loss" due to severe brain damage. From then on, he can only remember a few things. Although it seems to the police that this is an ordinary robbery case that happens every day, Leonardo's life has been completely changed since then. Dissatisfied with the police's hasty closure, Leonardo vowed to track down the murderer and avenge the tragic death of his beloved wife. However, the fragmented memory makes it difficult for Leonardo. He can only recall the past dribs and drabs with some small things such as tattoos and Polaroid snapshots. Moreover, whenever he finds some valuable clues, he must use all means to record them immediately, because it is very likely that after ten minutes, he will not be able to remember where he is or what he is doing. The investigation was difficult. Leonardo met a vulgar barmaid Natalia (Kerry Anne Moss), who seemed to know something that Leonardo was interested in, and a guy named Teddy (Joe Pantoli Yano), who claimed to be his former good friend. This guy was actually a real policeman. He helped Leonardo kill one of the two gangsters himself (one of whom was killed by Leonardo in the crime). But in fact, it wasn't his wife's death. The real cause of death was insulin overdose. Generally, we can refer to the situation of Sammy (another short-term memory patient, actually a microcosm of himself) in the film. Sammy actually didn't have a wife. Leonardo didn't buy insurance for his wife. His car belongs to a drug dealer, and the money belongs to that drug dealer. In fact, Leonardo only remembers what he wants to remember (possibly mental illness, which affects his memory). He dare not face the reality that he killed his wife. In order to survive, he can only deceive himself and live on the belief of revenge, otherwise his life will be meaningless, so it seems that he is being used by others in the film. In fact, Leonardo is also using others.
About the ending
The film has not completely solved all the mysteries, so everyone will have a lot of inferences. But basically, it can be confirmed that Lai (the hero) killed some people, and finally Teddy was not the real murderer, but a goal that Lai wanted to kill, and also the goal of Nitanli, but Lai's premeditated irrationality, and finding and solving the goal was the driving force for his continued survival. Teddy's clues made Lai a murder tool. The obvious evidence is what Teddy said at the end of the film (it can be suspected that he was lying, but he didn't have much need to lie at that time). Another detail is that Lai suddenly found a tattoo on his arm in the black-and-white clip-don't answer any phone calls, why can't he answer the phone? It can be guessed that Lai regretted it for some reason after killing someone, and his clues just came from the phone. Of course, the bloody photo can also tell the audience that he has killed at least one person-according to the film, that person should be the first real bad guy. As for the reason why this photo was not signed, we saw that Lai killed someone and didn't sign it, probably because of nervousness or fear of leaving evidence. The second inference is that Lai's wife was indeed killed by Lai's injection. You can pay attention to several clips. There are two scenes in which his wife was killed. The two times are different. The first time, Lai didn't take a gun, and he was knocked unconscious after entering the toilet, and a bottle containing blue substances was broken. The second time, Lai took a gun, fired a shot after entering, and then was pushed into the mirror. There is another scene, the first time is to pinch his wife's ass, and the second time is an injection. It can only be concluded that Lai's thoughts are chaotic, but we can boldly guess that Lai doesn't want to have real memories, and his illness really has psychological problems. At the end, Lai took Teddy as his next target, perhaps because he knew that he was used as a tool to kill people, and he hated him very much, so he had the plot of the first half of the film. All the black and white pictures in the whole movie are foreshadowing, while the color pictures in flashback belong to the climax plot. Perhaps Lai's real name is Sammy, and his own work is just his own imagination, resulting in inertial memory. Everything about his customers is actually his own.
