For the third time, Jennifer breaks free with the use of some sorcery involving a lighter that would almost definitely burn down the house in real life.
Jennifer uses a vase to hit Ryan over the back of the head. Conveniently, Detective Frank wakes up at the same time and somehow escapes from the sealed freezer. He's punctual, we'll give him that!
Why Jennifer has the overwhelming need to run to the woods without first making sure Ryan is indeed knocked out is beyond me, but here we are. Ryan comes to and chases after her but still can't catch her despite the fact she can barely walk.
A fight ensues between him and Jennifer that involves her trying (and failing) to use a large, dead tree to hit her stalker over the head. Luckily, Detective Frank shows up and takes on Ryan himself. He knocks the gun out of Ryan's hands and onto the ground, and Jennifer wastes no time in using it to shoot him twice in the chest. It was apparently that easy.
Just like that, the movie is over. Detective Frank moves away, putting his missing daughter's case to rest, while Jennifer opens and reads an emotional letter from her real husband while leaving town. I, for what it's worth, am exhausted.
