I know you usually have to suspend some disbelief in horror and sci fi movies, but there are limits, and this movie strains credibility to the limit right out of the gate.
The main character's loser brother is involved in a robbery that goes wrong, and his partner is shot and killed. He realizes there's evidence on the guy's phone that will incriminate him (these are not the brightest bulbs). His sister, who is a medical student, comes up with a "brilliant" idea: she will take propofol to fake her own death, she'll get taken to the morgue, and steal the phone.
Of course, propofol won't do that. There's a good chance it will really kill you, like it did to Michael Jackson, but otherwise you'll be quite obviously alive. Even if they thought she was dead, she was somehow confident that she would be put somewhere where she could easily find the other guy and his phone, rather than, you know, in a drawer that she couldn't get out of. Like they say in the commercial, "When you're in a horror movie, you make bad choices. It's what you do."
Without giving away any spoilers, the "twist" is pretty obvious - and completely unbelievable.
On the other hand, the acting is pretty good, and if you check your brain at the door, it's reasonably entertaining to watch.
