The Doctor, Amy Pond and Rory Williams arrive in the TARDIS in the belly of a missile packed with explosives. The missile's automatic defence computer identifies itself and detects the intruders are not Nabrili. The Doctor realises the missile is on its way to its neighbours, the Jells, with whom the Nabrili have pointless disputes and there is only about six and a half minutes to impact (943.8 Haldecs).
