Bobsledder Josh Gantz is accused of deliberately injuring a fellow competitor and might be thrown out of the sport-right before the World Cup. His younger sister Courtney asks her friends to help clear his name. Can amateur sleuths Trevor, Nick and Robyn find out who framed Josh? What is the meaning of the strange coded messages they keep finding around Olympic Park? Who eats orange bananas anyway? The kids must unearth the clues before Josh's championship dreams end up on ice.
