It's just a stream of fights - and canned scenes. There's no plot.
It's like the writers took all of the scenes from the other episodes, and randomly selected "one with Deeks and Kensi", "One with G and Sam", "One with Kensi in costume with a random "Bad Guy"", "One arguing with LAPD", "One in the Ops HQ", "Two in the boatshed". etc etc and then it was time for the next programme - and I have no idea how this episode wrapped up.
