Men in Black 3

In 2012, the alien Boris the Animal escapes a prison on the Moon to take revenge on Agent K, who arrested him in 1969. Boris travels to the past and kills K, erasing him from the present. Only J remembers his partner and goes back to 1969 to stop the crime. There he finds a young K and, with the help of Griffin, an alien who sees all possible futures, tries to install the ArcNet, a shield against an invasion, on the Apollo 11 rocket. In the race against Boris, J learns what happened to his partner that year.
