It was a cold, snowy afternoon when Colin received the call; a group of boys and girls had robbed Santa's Toy Shop. It was a well known fact, Colin and Riley, were the 2016 Nerf War Champions of Commerce, Michigan, and their cousin Bella, was the 2016 Nerf Crossbow Champion of Illinois. Is this the reason Santa placed that call to Colin? The cousins are called upon to solve a mystery. What happens next sets off a Nerf War of epic dimensions, and could cost them their reputations if they lose the war. Colin calls on their Nerf Club members for help and while they gather in Colin and Riley's basement, Bella is flying in from Illinois to join them on this quest. Can they save Christmas in time for all the good boys and girls? The challenge is on, and only time will tell.
