Doctor Who (2005) - 1x09 - The Empty Child (1)

After chasing a mysterious capsule through time, the TARDIS lands in London of 1941, where Rose is swept off her feet, and lands in the arms of a time traveller called Captain Jack.
The Doctor, on the other hand, follows a girl to a meeting of the homeless children of the Blitz during an air raid. Here a child in a gasmask is terrorising them by tapping into phones and making all sorts of things happen, all the while crying out for his mummy.
