When Dwight embarrasses Michael by punching him in the stomach at work, Jim organizes a lunchtime rematch at Dwight's Dojo. Meanwhile, Pam becomes annoyed at Jim when he gets too physical with her, Ryan updates the emergency contact information on a secret mission, and Michael tantalizes Ryan when the boss gets a hold of Ryan's cell phone number.

Dwight is tasked with hiring a part-time salesman to be Jim's substitute, so he rounds up a supergroup of his cronies, including his oddball beet-farmer cousin, Mose. Pam is left wondering who her new deskmate will be. Erin seeks her birth parents with help from Pete.
