Anna is an angel who, dissatisfied and frustrated with her mission, chose to relinquish her grace. She fell to Earth and was born as a human. Even when she lacked her angelic grace, Anna stilled maintained some of her angelic power, including degrees of superhuman strength and telekinesis. In one instance, it took five people to restrain her, and she used her mind powers against a demon who was about to attack her. When she retrieved her grace, Anna regained her angelic powers and abilities, but as a fallen angel she remained a hunted outcast.
Anna Milton is being held in a psychiatric institution (Connor Beverley Behavioral Medicine Center) because she has been trying to warn people that the apocalypse is coming, and that the voices she hears told her so. She actually does hear voices - those of the angels. She knows that Lilith is trying to break The 66 Seals and release Lucifer. When a demon tries to kill her she manages to escape, using some form of psychic power in the process. She takes refuge in the church in which her father was a deacon.
Ruby alerts Sam and Dean to her plight and they track her down. At her house, they find her parents dead. They then discover Anna at her church. She recognises them, and says she has heard the angels talking about Dean, as the one who may save them. She reveals that some of them don't like Sam. The demon Alastair then appears. He is immune to Sam's powers, and beats Dean, who had encountered him in Hell. In the chaos, Ruby takes Anna to safety, even though Anna is scared because she can see Ruby's demon face.
While the Winchesters and Ruby attempt to fight off Castiel and Uriel, Anna slits her wrists and draws an Angel Banishing Sigil in blood that casts the angels 'far away'. When asked, she states that she does not know how she knew what to do.
Later, with the help of Pamela Barnes, who places Anna in a hypnotic trance, Anna is revealed to be an angel. She is the former superior of Castiel and Uriel, who chose to rip out her grace and fall to Earth, where she was born as a human. Her disobedience is why the angels want to kill her.
Anna suggests that if she has her grace restored she will be able to protect herself. Sam determines where Anna's grace fell to earth by analyzing signs from the time of Anna conception on Earth. It was mistaken for a shooting star, and created a massive oak tree when it touched down. But when Anna, Ruby, and the Winchesters get there they find that the grace has been taken. Anna then gets a messages from the angels demanding that she be turned over to them by midnight or Dean will be returned to Hell.
She speaks to Dean of her frustrations with being an angel, particularly the blind obedience to God and the lack of emotion. Anna explains that she has never seen God, and that in fact only four angels have. She reveals that she knows what Dean did in Hell and encourages him to forgive himself. She then kisses him, and they have sex in the Impala.
Later Uriel appears to Dean in a dream and reveals the he is carrying Anna's grace in a vial around his neck. He reiterates the the ultimatum, and adds that either Anna will die, or Sam will.
When Castiel and Uriel appear in person the next morning, it seems that Dean has betrayed Anna and is handing her over. In fact, it is part of a ruse to bring the angels and demons (in the form of Alastair and his henchdemons) together to rid the Winchesters of both. A fight ensues, during which Anna steals her grace back from Uriel. She breaks the vial and shouts to Dean, Sam and Ruby to close their eyes. Her transformation back into an angel involves an overpowering white light, and destroys her human form and causes Alastair to disappear. When the light subsides, Anna is gone, presumably back to Heaven, where Dean imagines she is not happy.
As Dean is torturing Alastair, Anna appears and challenges Castiel about what he is doing and why he thinks God would order torture. She encourages him to rebel, but he rejects the offer. Later as his doubts grow, he calls on Anna and asks her for guidance, but she says he must choose his own course of action. After Uriel's treachery is revealed, Castiel refuses to 'convert' and follow Uriel's plan. Uriel attacks Castiel, but he is saved by Anna, who kills Uriel with her angel knife.
Anna visits Dean and Sam and tells them that Castiel was sent back to Heaven, and that Castiel knew something important. His vessel, Jimmy Novak, may know it too, and she encourages Sam and Dean to find him.Castiel turned her in. Because of the Enochian Sigils on his ribs, she can't find Dean and asks him to meet her. Castiel arrives instead, and suggests that she has Lucifer taking him as his vessel. Castiel says he is willing to kill Anna to protect Sam.
Anna vanishes, and travels back to 1978 intending to kill Sam's parents and prevent his birth. She is injured when she arrives in the past, indicating that she did not have the power of Heaven behind her when she time traveled. When Castiel takes Sam and Dean back in time to stop her, she lures John Winchester away from them by posing as his boss in a phone call. At the garage where John works, the body of a young man whose eyes were mysteriously burned out is found, implying that this human had spied on Anna’s true form, and was killed by as a result. Anna is unsuccessful in her first attempt on John and Mary's lives, and is temporarily banished by the Angel Banishing Sigil.
Anna next enlists the help of a younger Uriel to kill the Winchesters. However Michael arrives from the future, killing Anna for trying to interfere with his plans, and sending Uriel back to Heaven. In this episode, Anna wielded a blade with which she intended to kill Sam; Castiel pointed out it was not a blade that could kill Angels. This knife was knocked from her hand during one of the fights. She instead pulled a pipe from from a hole in the wall and used that to stab Sam. He was severely injured. However, Sam was healed when Michael returned the brothers to present day after Anna's death, so her mission was not accomplished.
- There is a discrepancy as to when Anna was born: on the Patient History form Sam looks at, it says that Anna's D.O.B. is April 13, 1985. However, later in the episode Sam says, In March '85, a meteorite vanished in the night sky over northwestern Ohio. It was sighted nine months before Anna was born and she was born in that part of Ohio, which would put her birthday in December of 1985.
- Anna never used a human as a Vessel. This is mainly because when she ripped out her Grace and fell to Earth she was reborn as a Human. She was then raised by Mister and Misses Milton. Anna Milton was afraid of her real father - her real father is God
- Her surname, Milton, may be a reference to the writer John Milton who wrote the epic poem 'Paradise Lost'. The poem describes the Fall of Man, the tempting of Adam and Eve and their being banished from the Garden of Eden. Milton also made reference to fallen angels, Lucifer, the war in Heaven, and the relationship between Heaven and Hell.
