Nancy and her friends are volunteering to help out families in neighboring towns who've lost their homes due to major flooding. Helping Homes is doing a project to build apartments for the displaced families and the two-time state basketball champions, the Lowell University Bullets arrive to help . . . but then awful things start to happen. Someone is sabotaging all their hard work-spray painting threats on the walls and tampering with the water valve to ruin the building-Nancy is determined to figure out who is doing this and why. Is all this trouble the product of a basketball feud . . . or something much larger?
