Enraged and filled with grief, they hatch a plan to exact revenge on the criminals responsible for Mari’s ordeal.

With the threat neutralized and justice served, the Collingwoods are left to grapple with the aftermath of their actions. Despite the satisfaction of avenging their daughter’s suffering, they are haunted by the trauma of what they have experienced and the toll it has taken on their family.
The film ends on a somber note as the Collingwoods come to terms with the consequences of their quest for revenge. While they may have achieved a measure of closure, they are left to confront the darkness within themselves and the lingering scars of their ordeal.
Overall, the ending of “The Last House on the Left” is a visceral and cathartic conclusion that explores themes of vengeance, justice, and the depths of human depravity in the face of unspeakable tragedy.
