Riz sometimes notices weird stuff. She can pick the twins apart, notices when people grow, and challenges the lunch staff when they change the cheese brand. Most people think it is odd, so she keeps her observations to herself.

But when Riz notices something different about her mum's cash, she speaks up only to get questioned by the police!

With her observations and a little help from some tech-savvy friends Riz leads the counterfeit bust. But can her team follow the right clues, or will it land them all in trouble?
