Michael stages an elaborate plan to finally get Pam and Jim over to his and Jan's place for a dinner party. Jim gets trapped into it and agrees to go. Dwight overhears and wants his invitation, too. Michael says he only has six wine glasses and with Andy and Angela going too, there's not enough room for Dwight.

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.
