The Winchesters

Before Sam and Dean, there were their parents, John and Mary. This is the untold love story of how they met and put it all on the line to save the entire world.

John and Millie are on different pages about his new interest in hunting and Ada tries to bridge the gap. Mary follows a trail from her father that points to the disappearance of a teenage boy in Topeka. Meanwhile, Carlos has a heart to heart with Mary as Latika dives into her books to identify the monster.

When Mary's next-door neighbor mysteriously goes missing, she and John start digging into the disappearance. During their investigation, John unexpectedly reunites with someone from his past. Carlos and Ada bond as they stakeout a potential lead for the demon's partner. Meanwhile, Latika taps into old folklore passed down from her family in hopes it helps Mary and John.

After the details of a veteran's death don't add up, Carlos brings everyone in to investigate and he shares a detail about his past that makes John see him in a new light. Mary finds an unexpected ally who has been hot on the trail of this monster and Latika tries to help Mary heal and find closure with someone she lost. Meanwhile, John's habit of running headfirst into danger leaves Millie worried for her son.

Hidden secrets from Ada's past comes to light when the gang goes undercover to look into a suspicious death. Still reeling from the last Hunt, Millie asks Mary to keep an eye on John as they split off from the others to get intel on the new case. Carlos and Ada's stakeout connects the victim to the next target. Latika's research comes up with some interesting results that lead John to be Mary's lifeline out of a sticky situation.

Mary gets a call from an old family friend who's looking for some help but when the team arrives, they learn that some crucial details were left out. While Latika struggles with being a Hunter and questions her future with it, John's eagerness, and commitment to the Hunt worries Mary. Carlos finds himself in a situation he's never experienced before and doesn't know what to do with himself.
