I only caught about the last 10-15 minutes of it. In those last minutes there was a man drug into an incinerator to be burned alive by ghosts who had suffered a similar fate (which is shown in a flashback). Those ghosts then turn to the remaining 3 survivors, one of the men yelling at the other two survivors, a man and a woman, to run, and take care of it, he’ll be fine and he takes off, the incinerated chasing after him. The man and the woman then run into a bathroom where the woman goes to throw a talisman/statue down the drain that would wash it out of the building and evidently save them when done. The other man however attacks her, stating that he’s been looking for it for quite sometime and it’s rightfully his. They ensue in a fight, and the shower heads turn on by themselves with the water slowly turning to blood. They fall down a set of short steps only to be met with a ghost doctor. The woman gets away, goes to grab the talisman only to be grab by the ghost doctor and thrown to a wall, knocked unconscious. The man she was fighting with gets back to where the woman, the talisman, and the ghost doctor is. Goes to get the talisman only to be grabbed by the doctor, lifted up by his neck and starts to have his head bashed against the wall where he tries to wake the woman up and tell her its okay, he’s back to himself, and to get the talisman.
The end has people walking out to two cars and the last shots are of the massive building from the back.
