- "Too slow!"
- ―Louis Kiet to Brian O'Conner
Following the capture of Ramsey, Kiet is the head of Mose Jakande's convoy transporting her to the terrorist waiting on the other end of the path in the Caucasus Mountains. When he realizes that they're being followed by Dominic Toretto and his crew, he attempts to kill them with the arsenal equipped on their vehicle. Despite his efforts, Dominic and the others are able to destroy the back of their transport, allowing Brian O'Conner to board.
Kiet fights Brian, preventing him reaching Rasmey before he is knocked unconscious. Kiet regains consciousness as their transport heads for the edge of the cliff. Both Kiet and Brian head for the back of the bus, but Kiet reaches the end first. He closes the gate that traps Brian at the front and mocks him for being "too slow". Kiet escapes from the bus right before it goes over a cliff.
Later Kiet helped Mose and his team by attacking Dom and his crew to receive God's Eye. He managed to avoid Mr. Nobody's bullets and shot him twice, though Mr. Nobody survived.
In Los Angeles, Kiet is sent after Brian following the destruction of the first radio tower that allowed Rasmey to partially hack her device, the God's Eye. He manages to intercept Brian half way to his destination to the next radio tower. Brian evades him at first, closing a a rolling shutter down behind him as he rolled into the next room, killing several of Kiet's men in the process with his firearm.
Half way up the stairway, Kiet intercepts Brian again and knocks him down. The two go sliding down the stairs on the door and crash below. Kiet attempts to crush Brian several times with nearby objects. However, at the last second, Brian hooks Kiet's belt to a weight and Kiet is dragged down into an elevator shaft.
Brian then taunts Kiet by shouting "Too slow!" at him as Kiet falls to his death.
