The Lazarus Effect has released a trailer.
Olivia Wilde stars in the horror film, which recalls 1990's Flatliners.
Wilde plays a doctor who is leading an experiment to raise the dead.
But when she becomes the latest test subject after a fatal accident in the lab, the woman who comes back may not be the same one that left them.
Donald Glover, Evan Peters and Mark Duplass also feature in the David Gelb-directed movie.
The Lazarus Effect will arrive in US cinemas on February 27. A UK release date is yet to be announced.
