Kui tulnukad püüavad kinni klassikaliste telekamängude videod ja väärtõlgendavad neid sõjakuulutusena, ründavad nad Maad videomängude kujul. President Will Cooper (Kevin James) teab, et ta peab kasutama sarnast strateegiat, mistõttu palkab ta planeeti päästma oma lapsepõlvesemust endise videomängutšempioni ja kodukinopaigaldaja Sam Brenneri (Adam Sandler), keda täiendab vana kooli telekamängufännide tiim (Peter Dinklage, Josh Gad), ning militaarspetsialist (Michelle Monaghan).
From the beginning of all, there were battle gods called "Gourikishin" who team up with human partners they revere as "Oyakata" as they go through battle called "Kamizumo".
