In 2007, Sally Sparrow, intrigued by a message written to her under peeling wallpaper about “the Weeping Angel”, explores the abandoned house Wester Drumlins with her friend Kathy Nightingale. Kathy is sent back in time to 1920 by a Weeping Angel statue. At that moment, Kathy’s grandson, Malcolm, delivers to the house a message from 1987 about the long life Kathy led. Before leaving, Sally takes a Yale key hanging from the hand of a statue. Sally visits Kathy’s brother, Larry, at work to tell him that Kathy loves him, as the letter requested. Larry explains that he has been documenting an “Easter egg” in seventeen different DVDs containing a video message of a man having half of a conversation with the viewer. Larry gives Sally a list of the DVDs. Four Weeping Angel statues follow Sally to the police station, where they take an impounded fake police box and send DI Billy Shipton back to 1969. The man in the Easter egg, a time traveller called the Doctor, has also been sent to the past, and asks Billy to relay a message decades later. Billy puts the Easter egg on the DVDs. In 2007, a much older Billy phones Sally to visit him on his deathbed in the hospital. Before he dies, Billy instructs Sally to “look at the list”. The list is Sally’s own DVD collection.
Sally and Larry return to the house and play the Easter egg on a portable DVD player. Sally discovers she can converse with the Doctor in 1969, as he possesses a copy of the complete transcript that Larry is currently compiling. The Doctor explains that aliens called Weeping Angels turn to stone statues when any living creature observes them. He fears they are seeking the vast reserves of time energy in the police box, which is his time machine the TARDIS, and could cause enormous damages as a result.
A Weeping Angel pursues Sally and Larry to the basement where the TARDIS is. Sally and Larry use the Yale key to hide inside, while the four Weeping Angels attack. Larry inserts a now-glowing DVD, which also functions as a control disk, in the console’s DVD player. The ship returns to the Doctor, while leaving Sally and Larry behind. The Weeping Angels standing around the TARDIS get tricked into looking at each other and are permanently frozen. A year later, Sally and Larry meet the Doctor prior to him being stuck in 1969. Sally hands the Doctor Larry’s transcript, and warns that he will need it.
