Boris adlı bir mahkum, kendisini hapse atan Ajan K'den (Tommy Lee Jones) intikam almak için, hapisten kaçar ve zamanda geri dönerek tutuklanmadan öncesine döner ve Ajan K'yi öldürür. Arkadaşı Ajan J (Will Smith), bu olayı engellemek için o günlere, yani 1969'a seyahat eder. Ancak genç K (Josh Brolin), durumun ciddiyetini anlamakta güçlük çekmektedir. Ajan J hem K'yı ikna etmek, hem de arkadaşını kurtarmak durumundadır. After breaking out of a moon-based maximum security prison, Boris the Animal decides to go back in time and eliminate the person who arrested him - Agent K. When he does so, Agent J realizes that the time line has been changed and he too travels back to July 15, 1969, the day before Agent K is killed. After overcoming some disbelief, J manages to convince K and others of just who he is and why he's there. With the help of a being who can see all time lines, they track Boris down. J also learns a secret, something K had never told him.
