The Netflix horror thriller Aftermath’s movie ending is more than a little confusing but once explained, the truth behind Otto and how he lived so long in Kevin and Natalie’s house becomes clearer. Directed by Peter Winther, Aftermath stars Ashley Greene, Shawn Ashmore, Britt Baron, Diana Hopper, Ross McCall, and Sharif Adkins. Released on Netflix in 2021, Aftermath is about Natalie Dadich (Greene) and her husband, Kevin (Ashmore), who fall victim to disturbing events after moving into a new house. Kevin becomes aware of the property while cleaning a murder-suicide that took place there.
