Michael gets worried after a request from Jim, and Pam’s busy with wedding planning. Darryl’s worker’s compensation claim makes Dwight suspicious.
Corporate honcho David Wallace (Andy Buckley) floors the staffers with news that not all will receive raises for the year. Elsewhere, Jim pushes Dwight too far, so Dwight sets out to form office alliances. And Pam focuses on her wedding-gift wish list.
The Dunder Mifflin staff are in Niagara Falls for Jim and Pam’s wedding, with the understanding that her pregnancy is a forbidden discussion topic. Michael, Dwight, and Andy all hope to find romance of their own among the guests.
Dwight and Andy have Michael believing an insurance saleman is a Mafioso. Pam has a painting accidentally destroyed by Erin.
