When Barbara visits the U.S. capitol – Washington, D. C. – she is surprised to discover it's a city that's about much more than politicians in suits. Her teen co - host, up - and - coming rapper Marky, shows Barbara his city is hip – with hip hop. Marky takes Barbara to many of D. C.'s famous and historical landmarks – from the White House to Arlington Cemetery to a renowned chili restaurant – while composing lyrics on the spot about each site they visit for a rap duet they record together in a professional music studio.
