The Void (2016)

James escapes from a farmhouse into the woods, where two men, Vincent and Simon, shoot a woman and set her on fire. Deputy Daniel Carter finds James crawling along a road and takes him to a local hospital, partly abandoned after a fire. His estranged wife, Allison, is a nurse there, working with Dr Richard Powell and a small staff and patients, including a pregnant young woman, Maggie, and her grandfather, Ben.

Daniel finds nurse Beverly, in a trance and with her face cut off, killing a patient, and shoots her. Robed cultists surround the hospital. Beverly's corpse turns into a tentacled creature. Vincent and Simon arrive, hunting James. In the chaos, James stabs Dr Powell, who seems to die, and the creature kills a state trooper.

Allison goes to the basement for medical supplies and is captured by Powell, who is alive again. Daniel discovers that Powell is the cult's leader. Powell explains that he found a way to defeat death after losing his daughter, Sarah, and that something is now growing inside Allison. In the basement, James is killed by deformed, reanimated corpses.

Maggie goes into labour, then kills her grandfather, revealing she is carrying Powell's creation. Daniel finds Allison mutated, with a creature growing out of her, and is forced to kill her. Powell offers to bring back Daniel's dead child if he lets go.

Maggie's body bursts open, giving birth to a creature meant to be Powell's daughter. Vincent sacrifices himself so Simon can set it on fire. Daniel refuses Powell's offer and tackles him, and both fall into the void. Simon escapes and finds himself back in the hospital with Kim, the only other survivor. Daniel and Allison are seen holding hands in another world, beneath a giant black pyramid.

What is the void? A doorway to another dimension, home to ancient beings "older than time". Powell uses it to try to defeat death.

What is the triangle? The symbol of the cult and of the other world. The filmmakers deliberately left its meaning open.

What did Powell want? To bring back his dead daughter, Sarah, through monstrous births and transformations.

What happens to Daniel? He tackles Powell into the void. In the final shot, he and Allison walk hand in hand in another world beneath a black pyramid, suggesting they are together after death.

Who survives? Simon and Kim, who end up back in the hospital.
