CHERUB is basically for those who don't know about a government orphanage that orphans children until 18. After that there's M15, who are the spy's over 18. You had came from a poor family, so you didn't own much. You woke up, it was morning, the room was cool, white walls and much more. You got out of bed and felt the coolness. Maybe too much. You looked down. You were naked. You looked for your clothes. You only find some underwear, camouflage pants, army boots and an orange t-shirt with a winged baby. You decide to go out. You meet several people and ask "Um... Where am I?" But they all say "I can't talk to the orange ones". But some give you tips on where to go. You follow them and meet an old man they call Mac (I don't know much about him, sorry). He explains everything about CHERUB to you.
