In this sequel to Let Me In, Jessica (Reagan Foxx) knows that her old life with her family is completely ruined, so she has agreed to do whatever her demonic doppelganger Tess (Shay Sights) wants. As Jessica drives down the road with Tess riding beside her, Tess says that Jessica needs to go through an initiation first. Jessica doesn't know what that means, but then they spot three men (Isiah Maxwell, Mighty Dee, and Slim Poke) who are stranded because their car ran out of gas. Seeing the perfect opportunity, Tess tells Jessica to 'help' them. Jessica catches on, so she pulls over and works with Tess to seduce the men and then complete the sinister initiation. Once the initiation is complete, Jessica hungers for more, and Tess knows what their next step should be. They turn their sights on a family: Linda (Lexi Luna), her wife Teri (Sophia Locke), and their stepson Craig (Tyler Cruise), corrupting them as the next part of Tess's plan to build an army of lookalikes...

Jessica is having a wonderful family game night with her husband Rod, her stepson David, and David's girlfriend Amy. Everything seems to be wholesome and going great until there's an unexpected knock at the door. Jessica excuses herself to cheerfully answer the door, then gets the shock of her life when she sees another woman smirking back at her. It's like looking in a mirror... and it's clear from the horror on Jessica's face that she doesn't like who is looking back at her. It seems like the past has caught up with Jessica and she's about to ruin every relationship she has with her family... and the relationship she has with herself.
