The upcoming episode of the long-running The CW series "Supernatural" will be a little early for Valentine's Day, but it will surely give the viewers chills. The Winchester brothers will be dateless, as their job once again ensures that they will be too busy to unwind.

In "Love Hurts," CarterMatt reports that a string of murders will send Sam (Jared Padalecki) and Dean (Jensen Ackles) on investigation mode on Valentine's Day. Instead of having a date of their own, they will be dealing with an ancient curse, one that can send a person to the other side with just one deadly kiss. Once it touches the victim, there is no escape. The situation will be doubly problematic, as the brothers attempt to prevent people from being pecked to death on the one day it seems illegal not to kiss. Will they succeed?

Last episode, Castiel's (Misha Collins) daughter, Claire (Kathryn Newton) was giving Jody (Kim Rhodes) a huge headache. She did not want to go to school. The teen just wanted to roam around, trying to find supernatural beings she could take down. It got so bad, she even accused ordinary schoolmates that they were paranormal. When Sam and Dean went to see the sheriff, they discovered that the other girl, Alex (Katherine Ramdeen), had a boyfriend.

When the principal to the school the girls attend turned up dead, Sam and Dean knew they were facing something dark. It turned out the campus custodian was a turned-vampire. He hailed from Alex's hometown, the one with the vampire's nest that the Winchesters eradicated. He was one of Alex's victims and he wanted revenge. Worse, he had an accomplice. Alex's boyfriend was a vampire, and he was ordered to kidnap the three women.

Sam and Dean eventually defeated the creatures and made the girls realize how hard it was for Jody to take care of them. The episode ended on a positive note, with Claire and Alex cooking their adoptive mother dinner.

Supernatural" season 11 airs Wednesdays at 9 p.m. EST on The CW.
