In 1997, the survivors of the nuclear apocalypse continue a merciless war against the robots and machines that they themselves created. To put an end to John Connor who leads the men's resistance, two "cyborgs" are sent into the past. Their mission: to cut down young Connor. The first model of the "Terminator" series failed in 1984. The second, a more efficient model in morphing liquid, sets off in pursuit of the child and his mother, Sarah, in the nineties. For their part, the men of the future have sent a Terminator to the past tasked with protecting young Connor. The duel of the robots will then take on titanic proportions. And, while the child will teach this Terminator the rudiments of humanity, his mother will try by all means to prevent the creation of the first intelligent machines. With the help of the Terminator they have educated, they will fight to influence the future...
