In the movie Independence Day: Independence Day: Resurgence, twenty years ago the Earth almost disappears at the hands of the extraterrestrials. The men narrowly avoided being swept from the face of the Earth and learned the lesson.
Therefore, they gathered the technology of the aliens and formed an alliance, since they expected the aliens to attack again, although the truth is that they expected the attack to happen earlier.
Now the aliens are back, but this time the men are ready, or at least that’s supposed, since at the time of truth they realize that the technology they have is obsolete, something logical if we consider that they have passed twenty years.
Again, the Earth is on the edge of the abyss. The only hope lies in a group of brave men, who are going to risk everything to save our planet again, although this time seems almost impossible, because the technology of the aliens is incredible.
