This is the office of a small branch of the "Dundermingtian6.comMifflin" paper company. Under the leadership of Michael (Steve Carell), a regional manager with a very off-line mind, a group of office workers lead weird lives every day. Jim (John Krasinski) is a witty, clever prankster who comes up with different ideas all day to toss the pedantic colleague Du Weite (Rainn Wilson) sitting opposite him. The latter is always annoyed and secretly does bad things to Jim at work, and regards him as the biggest competitor for promotion; Jim's prank partner is the front desk girl Pan (Jenna Fischer), and the two make endless laughter, but Pan already has a fiance, and Jim can only send emotions and stop courtesy when he is moved by her. There are also Angela (Angela Kinsey), an older single woman with a weird temper, Oscar (Oscar Nuñez), a gay accountant discriminated against by Michael, and Ryan (BJ Novak), an intern who is desperately trying to fit in. Regardless of whether their personalities match or not, they all agree that Michael is the biggest bad guy in the room... This drama is the American version of the BBC sitcom "The Office".
