Martyrs

Martyrs (2015) is an American horror film you can watch online on iFILM. Ten-year-old Lucie is found a year after she vanished, too terrified to say a word about what was done to her. A decade passes, but the nightmares never loosen their grip.

Now grown, Lucie (Troian Bellisario) and her childhood friend Anna track down the people who took her, determined to learn the truth at last. What waits past that answer isn't release — it's another trap, one almost impossible to escape. This is the American remake of the notorious 2008 French film; directors Kevin and Michael Goetz dial back some of the original's savagery and lean instead on mystery and dread.

It's horror with a hard edge: abuse, revenge and pain handled without flinching, though this version softens the source. It works for viewers after bleak psychological terror wrapped in a detective puzzle rather than another slasher. The squeamish should keep walking. Stream Martyrs (2015) online on iFILM.
