The "Monster of the Week" storyline returns on the next episode of "Supernatural" Season 10. The CW Network has released a video clip for episode 4 titled "Paper Moon" teasing about Sam (Jared Padalecki) Dean's (Jensen Ackles) undercover investigative work on werewolf attacks and who their suspect is.

The next "Supernatural" episode will have the Winchester brothers back to doing what they do best which is hunting. In the "Paper Moon" video clip, Sam and Dean conduct an investigation on the brutal murders that happened.

The local sheriff admits that the authorities are glad to see the undercover Winchester hunters taking on the mysterious case. When Sam asked if there is anything weird on the murders, the local sheriff shared that they were all similar.

"Folks torn clean through. Hearts absent," the local sheriff stated. "Hearts absent as in?" Dean asked and the local sheriff responded that they have most likely been consumed. Then, Dean asks if there were witnesses at the scene.

The local sheriff revealed that there is a witness named Tommy but he is not really a reliable one. According to the drunk witness, he saw a girl also getting torn up. However, the local sheriff told the Winchester brothers that no body, no DNA or no blood trail was found during their investigation to confirm that there was a second victim.

"Hearts missing, sounds wolfy to me right?" Dean tells Sam and the younger Winchester agrees. "Do you think it was the girl?" Dean asks. Sam simply responds that the two of them should find out. Watch the "Supernatural - Paper Moon" video clip below.

The official synopsis for "Supernatural" Season 10, episode 4 in a Hypable report reveals the string of werewolf attacks that Sam and Dean will investigate on points to werewolf Kate (Brit Sheridan), the girl that the Winchester brothers let go in "Supernatural" Season 8, episode 4 titled "Bitten." The "Supernatural" fans can recall that Kate was able to convince Sam and Dean that she will only feed on animals and not hurt humans so she can continue to live in peace.

Find out if werewolf Kate is really responsible for the attacks or she is being set up on "Supernatural" Season 10, episode 4 titled "Paper Moon." The brand new episode is scheduled to air on Tuesday night, Oct. 28, at 9 p.m. ET on the CW Network.
