Supernatural takes viewers on a terrifying journey into the world of the unexplained. Sam and Dean Winchester lost their mother to a mysterious and demonic supernatural force. Subsequently, their father raised the brothers to be soldiers. He taught them about the paranormal evil that lives in the dark corners and on the back roads of America... and he taught them how to kill it.
With their father gone, Sam and Dean are now facing an all-out demonic war. As they work to stem the rising tide of demonic activity, they continue to travel the country, battling the supernatural wherever they go - and battling their own demons that live within.
01 - Lazarus Rising
Twenty-five years ago, Sam Winchester (series star JARED PADALECKI) and Dean Winchester (series star JENSEN ACKLES) lost their mother to a mysterious and demonic supernatural force. Subsequently, their father raised them to be soldiers. He taught them about the paranormal evil that lives in the dark corners and on the back roads of America...and he taught them how to kill it. Now the Winchester brothers crisscross the lonely and mysterious back roads of the country in their '67 Chevy Impala hunting down every evil supernatural force they encounter along the way.
In the fourth season premiere, it's been four months since Dean was dragged away by the hounds of Hell, the result of a deal he made with the Crossroads Demon in exchange for his brother's life. Now, Dean wakes up in a pine box. He's been freed from Hell, but he doesn't know how or why. He has a joyful reunion with Sam and fellow demon hunter Bobby (recurring guest star JIM BEAVER), but it isn't long before the three start to really wonder what exactly pulled Dean from Hell - and what it will want in return.

Sam and Dean are stunned when the spirits of Meg (recurring guest star NIKKI AYCOX - "Cold Case," "Ed") and Agent Henricksen (recurring guest star C. MALIK WHITFIELD - "The Guardian") appear and accuse the Winchesters of failing them.

However, that shock turns to amazement after he runs into a young John Winchester (guest star MATTHEW COHEN - "South of Nowhere," "Medium") and Mary (guest star AMY GUMENICK - "Greek") who have just fallen in love. Dean isn't sure why he was sent back so he begins to enjoy the time with his parents and newfound grandfather (guest star MITCH PILEGGI - "The X-Files," "Stargate: Atlantis"), who may be hiding a secret that is key to Sam and Dean's entire predicament.
04 - Metamorphosis
Sam and Dean discover that Jack Montgomery (guest star DAMEON CLARK - "24," "Prison Break," "Dragon Ball Z" series), a family man, is turning into a Rugaru, a creature that starts as a human but changes into a flesh-eating monster. The people who are infected don't understand what is happening until they turn into cannibals and eat another person. Understanding what it is like to be a victim of a twisted destiny, Sam believes he can reason with Jack and convince him to control his urges. Dean doesn't think Jack's animalistic behavior can be subdued and decides the only honorable thing to do is to shoot him.
05 - Monster Movie
Shown entirely in black and white, Dean and Sam investigate several murders at Oktoberfest. The first victim was found with bite marks on her neck, much like a vampire would leave, while the second victim has wounds that look like a werewolf attack.
