Tonight on BBC America at 9PM/8PM Central, the Doctor, Amy and the TARDIS are hurtling toward space and time to the season finale, and it starts now. First we see Vincent Van Gogh struggling against his demons, and then Sir Winston Churchill looking at a painting. Then we see River Song, incarcerated, being alerted by Winston about a crisis. She escapes, and goes after Vincent's painting. She comes across the future Queen Elizabeth X, whose reaction tells us things are not good. So River goes looking for assistance.
And then Amy and the Doctor are in the TARDIS, Amy looking at the engagement ring she found in the Doctor's pocket, not realizing it is her own. The Doctor sees a message from River, and follows it all the way to Stonehenge. There he meets up with River, and we finally see Vincent's painting - the TARDIS exploding! The Doctor hears something, some sort of signal, and the trio venture to "the Under-henge." They find the Pandorica, a super-strength jail cell to hold the most dangerous and terrifying of prisoners. Amy thinks it reminds her of Pandora's Box, filled with all the evils of the world. They soon discover it is starting the process of opening...
But Stonehenge is transmitting the signal, and soon the Earth is surrounded by spaceships, Daleks, Cyberships, and every enemy the Doctor has known. River leaves to gather the Roman soldiers to help the Doctor prepare to defend against whatever is inside. Amy brings up the engagement ring to the Doctor, who tells her it is a memory, and if something is remembered, it can return. River sends a volunteer centurion, and goes off to check on the TARDIS. Back at Stonehenge, the Doctor and Amy are attacked by a stray arm of a Cyberman. Once the Doctor has the arm under control, the head attacks Amy, and drugs her. Then the body returns. It goes after the wobbly Amy, who is saved by the Centurion, who reveals himself just as Amy passes out. It is Rory.
The Doctor takes to the microphone, challenging all his enemies to take him on. They back off. Amy wakes up, and Rory realizes Amy doesn't remember him. He is crushed, and laments to the Doctor, who gives him the ring and tells him to go get Amy. Meanwhile, the TARDIS lands on Earth, outside of Amy's house, so River goes in to check things out. She finds her old books, with tales of the Roman invasion and Greek Mythology. Amy starts to recognize Rory. The Doctor and River start to figure things out.
Is anything real? Or is it all Amy's memories? Who will protect the world, the universe? And who are they protecting it from? Truly, we won't find out all the answers until the finale next week, but you will find out some of them. To check out Doctor Who on the web, click here. And watch the trailer below.
