|Vincent and the Doctor||The Pandorica Opens|
A mysterious force blocks the TARDIS - with Amy inside it - from landing, keeping it stuck in a materialization loop. It's up to the Doctor to work out what that force is, or Amy will be lost forever along with the TARDIS.
As he investigates, the Doctor learns of a house with a staircase which people walk up but never come back down. To solve this mystery, the Doctor must pass himself off as a normal human and share a flat with a fat bastard.
