Jack is in hospital. There's something wrong with his leg. But when he catches a glimpse of his X-ray he doesn't expect to see a huge squirming thing writhing around inside it. It turns out he's not alone - two of his best mates have the same problem. The doctors won't tell them anything. Jack's worried. Then the burning and hissing starts.
