A foreign movie is about alien life invading human body and then spreading widely.

Plot introduction

A huge fireball lit up the sky in Washington, D.C., and the "Patriot" spacecraft disintegrated in a big explosion, and fragments were scattered in every corner of the United States ... However, this did not cause much panic among the citizens, because "authorities" immediately informed everyone on TV: "Everything is under control." But no one expected that a strange and strange life in space attached to the debris produced by the explosion reached the earth. Its strength is unknown, but it can withstand the double test of extreme cold in space and burning in the atmosphere. The first person to touch it will be the first person to be changed-I believe that if it can be predicted, no one will want to fall into this panic.

At this time, Carol Beenaert, a psychiatrist in Washington, D.C., didn't realize the patriot explosion, but she was the first person to feel this change, because something strange happened around her: one of her patients trembled with fear for no reason, because she felt that her husband had been replaced by a stranger who looked the same; The most terrible thing is that even the violence in the streets at night is almost zero, and the expressions on people's faces are increasingly replaced by ruthlessness ... Not only that, strange substances from outer space have entered Carol's home, and it is hidden in the Halloween candy her son Oliver got-it turned out to be a living body, alive.

Carol told her doubts to her closest friend and colleague Ben Trescoll. Although the Washington government seems indifferent to this, Carol firmly believes that something terrible is happening. The official statement became a disguise of the truth: they said it was just a new type of flu. Before she realized what had happened, Carol made a fatal mistake. She sent Oliver to her divorced husband and let them stay together all weekend. You know, Carol's ex-husband is a senior official of the CDC, responsible for investigating the explosion and the first person to arrive at the scene.

When the life attached to the debris eventually turned into a virus and began to spread, Carol also realized that the government's stupid and helpless emergency measures would only make everything worse ... Single cell regeneration from outer space, whose source is uncertain, will attack its DNA while the host is asleep, and then copy the host again to generate a brand-new life that looks like the host and speaks the same. However, the difference is that this life form will slowly dry up human emotions. Carol found that after only one night, the people around her became another creature. They only know how to carry out one instruction, that is, to find a new source of infection and then take over the whole earth.

Carol has understood the truth. What she needs to do now is to stay awake at all times. In despair, she walked into the changing world, looking for her son Oliver ... hiding among the infected people, Carol tried to calm herself down without any emotional fluctuations. But most importantly, she can't sleep.
