Not much is known about the special at the moment, but going by the information in the pictures we can see that there will be at least TWO Amy Pond's and somehow the TARDIS will manage to land inside the TARDIS.
The special will last for six minutes and will be shown on the evening of Friday March 18th. Earlier this week, Moffat had this to say about it.
"It's not a spoof. It's in the style of the ones that we've done for Children In Need, so it's taken seriously as a proper bit of Doctor Who. It's funny, but not a sketch."
