It's a sunny day. You're walking down the street, enjoying the warmth. Maybe you might get an ice-cream and get a bit of a colour, right? The world's your oyster. You're free to go about your business for the next little while. WRONG.
We don't want to give it away, but keep an eye on the guy walking down the street on the right in red. See the picture above? We've marked him. Watch and be amazed / horrified.
