One day in the 21st century, mysterious aliens suddenly invaded the earth. The strange thing is that all aliens appear in the image of pixel video games popular in the 1980s. All objects and humans touched by them are pixelated without exception. Will Cooper (Kevin James), the current US President, felt the seriousness of the situation and hurriedly called Sam Brenner (Adam Sandler), his playmate who was very good at arcade games. Under the guidance of another weird friend Ludlow Limentov (Josh Gad), they seemed to understand the true identity of the aliens. The invasions came one after another, and this group of big boys found their former nemesis Eddie Plant (Peter Dinklage) and jointly launched a 3D pixel war with the aliens disguised as games. The earth is in danger, and this is really not a game that people can take lightly...
