History

Mary Campbell is the daughter of Deanna and Samuel Campbell. Mary was raised to be a hunter by her parents from a young age. She was very close to her cousin Maggie, who was killed in 1971 by a vampire. Following Maggie's death, Mary has decided to leave hunting, a fact she argued with her father about before he suddenly disappeared while on a hunt. At the time of his disappearance, her parents were separated, having had relationship difficulties since Maggie's death. She had previously stayed with hunter Tracy Gellar in Kalamazoo when her parents were having marriage issues.

Episodes

1.01 Pilot

Mary's father Samuel has gone missing while on a hunt. In her last conversation with him, he sounded afraid, and told her she needed to retrieve a file from an address in Lawrence; information he'd obtained from Ada Monroe. At the location she finds John Winchester, who has been directed to the same address by a letter from his father, handed to him by a mysterious man.
John has a key that opens the magically warded door, which leads to a clubhouse for a group called the Men of Letters. Mary finds the schematic that her father, was after, while John finds items belong to his father who was apparently a member of the secret society.
With help from her friends Carlos and Latika Dar, they follow Samuel's trail to New Orleans, and in a tomb guarded by a Loup-Garou retrieve a box that can trap and kill monsters.
Ada tells them Samuel Campbell was looking for a way to defeat a supernatural being called the Akrida which is trying to invade Earth.
