Terminator 2: Judgment Day

Ten years after Sarah Connor survived a deadly cyborg sent from the future, her ten-year-old son John becomes the next target. A reprogrammed T-800, identical to the machine that once tried to kill Sarah, is sent back to protect him from the T-1000, a more advanced shape-shifting cyborg. Together, John, Sarah, and their unlikely protector fight to prevent Skynet from triggering a nuclear apocalypse.
