The video sees Agent J (Will Smith) enlist the help of an electrics shop owner (Michael Chernus) as he attempts to travel back in time and stop his partner Agent K (Tommy Lee Jones) from being assassinated.
Once back in time, J encounters young versions of K (played by Josh Brolin) and Agent O (played by Emma Thompson and Alice Eve).
Upon the film's theatrical release, director Barry Sonnenfeld hinted that the series could be rebooted in the future.
