Twelve-year-old Alexis "Alex" Evins is a loner, a tomboy and a first-class prankster, following in the not-so-glorious footsteps of her older twin brothers, Parker and Nick. When the Evins siblings play a prank that goes just a tad too far (resulting in setting a neighbor's sofa--and hair--on fire), their dad decides it's time for some tough love. He signs them up for an after-school program called Champs!, which guarantees that it will turn any kid into a well-rounded success. Alex, Parker and Nick all must pass the course together, or else it's off to St. Ignacius private school (aka St. Ignasty).
At Champs!, Alex encounters more than a few nemeses, including the Champs! coach, Sharon Success, mom of Alex's classmate, the totally perfect and totally annoying Emily Gold, and the ultra-competitive Chloe Stroupe. After weeks of intense classes, the Evins sibilings are soon faced with the Champs! Championship, a test of teamwork, leadership, and responsibility. Alex and her brothers are determined to win. But when an earlier misstep threatens all their hard work, Alex finds herself scrambling to make things right.
Can the "evil Evins" actually pass this course in one piece? Or are they destined for an epic fail?
