The International Friendship Club is sponsoring a fun weekend—but Nancy finds a melting pot of sabotage!

For Nancy and her friends, Worldbeat Weekend at Emerson College is supposed to be a good time. Nancy gets to spend time with her boyfriend, Ned, and everyone plans to enjoy music and food from around the world. But the two candidates running to be the next president of IFC are from rival countries, and when they accuse each other of smearing their campaigns with dirty tricks, the chaos begins.

Missing money and collapsing tents are just the start of the trouble. As tensions rise, the weekend spirals toward disaster. The local press is sniffing around. A public scandal would ruin IFC, and only Nancy can uncover the clues to track down the culprit in time!
