Trying not to go crazy in the process, a woman hoping to get to the bottom of the existence of a perceived supernatural entity that she believes is responsible for her father's death recruits her sister into the ordeal only to find the both of them in the grip of something they weren't expecting.
Overall, this was a pretty solid and enjoyable effort. One of the better aspects here is the film's overwhelming sense of atmosphere and thrills present here which is handled rather well by the film's setup. Keeping things relegated more to a psychological component regarding whether the spirit tormenting her is real or not, the film can play exceedingly well with the idea of slipping sanity following the myriad of encounters she has with something all in the name of her fractured and guilty conscious getting the best of her. These brief, fleeting encounters offer the kind of genuine uncertainty in their realness and believability that causes so much of the film to be written in that manner and helps to further the relationship issues between them that grow throughout the course of the film. This connection that builds up over the course of the film is also handled rather nicely even if it results in the main downfall of the film as a whole. With the film's minimalist approach keeping things grounded with the two sisters being the majority of the characters on-screen and putting everything in pretty much one spot, there's not a lot of energy present here with the main focus instead being on understanding the relationship between the sisters. There's far more work here building up their attempts at dealing with the concept of the ghost being real and how its presence has affected those around her which comes at the expense of special effects shots or concepts so it can feel like the film has some padding to bump up the already brief running time. It's not enough to hold it down but does affect it.
