This twisted thriller will keep you guessing until the bitter end. Waking up in a pit of dead bodies with no memory, a man joins forces with a group of strangers. Together they must figure out who is behind the mysterious mass killings. But suspicions give way to violence, as they piece together their identities and discover a much more vicious and deadly threat to their survival. A must watch!

Zombies with a difference
Verified purchase
Starts really well, a man wakes up in a mass grave with total amnesia. He's stuck until a mute oriental woman lowers a rope and pulls him out. The film is a tense thriller to start with but eventually sinks into shock tactics. Well acted, well-paced, but can't someone come up with an idea that isn't basically Aliens, Predator, or zombies? What if it is a plague which has killed off most of humanity and left a lot as crazed killers? It's still a zombie gore fest. You may find it worth a watch but I wouldn't watch it again.

Mystery Horror with Strong Start but Weak Ending
Verified purchase
The trailer does give you a bit of an idea about what to expect with this film but also might lead you to think this is more of a zombie fest survival horror than what it actually is. It's more of a thriller mystery with some gore rather than an out-and-out horror as the film focuses more on the mystery of the unknown with the people in the unusual situation of each finding themselves with no memories in a strange house surrounded by death and bodies. It starts really well with this as there is lots of suspicion and doubt and the unknown, so it creates an edgy environment where you don't who to trust or what to think, but some aspects do get a little predictable as the film progresses (or did for me, at least).

None the less the film did otherwise develop fairly well if a little slowly here and there but it seemed to lose its way towards the end a little and definitely could have finished with a much stronger ending considering how well it started.

I'd give this 3.5 stars as it was certainly watchable as a one-off but four stars would be a bit too generous and I wouldn't go out of my way to recommend it.

Gripping horror

The synopsis of this film is enough to make you want to watch it. A man wakes up in a pit full of dead bodies. He has no memory of how he got there. After escaping he enters a house full of strangers who are also extremely agitated and just like him they have all lost their memory.

The elephant in the room though is that if they are all alive then who has killed all the people? That is when the fun begins. What I really liked about this film was that it continued to surprise, I got it wrong every time I tried to guess what was coming next and that for me is a real plus.

The cast are a brilliantly disparate group too and they all do an excellent job of keeping you right on the edge of your seat. The pacing is just right; the make up spot on and even the music gets the mood just right. There is not a lot not to like here (sorry about the double negative). It was filmed in Hungary but has a feel of being American despite a cast that is International. If you like your horror’s to be a bit on the dystopian side then you should have a look at this.

Fantastic Movie at £3 delivered (new) - what's not to love!
Verified purchase
Gonzalo López-Gallego, who made Apollo 18, has delivered in spades with this low budget movie. For less than a fiver (£2.75 😲) new, I just thought it would be "just" OK.
It was fantastic, I loved it and only gave 4☆ as it has no extras.
And to think I paid 4 times this for The Nun, which was pants!!
Simple film making at its best, and at this price I hope you will be as pleasantly surprised as I am - enjoy 😀

Gripping Stuff

Finally, an entertaining film worth watching. I have sat through and nodded off through so much rubbish recently that I was extremely grateful to find this horror/mystery/thriller. Thoroughly gripping, kept me guessing, extremely well acted and a suitably atmospheric musical score. Thank you!

Good film. Highly recommend and Sharlto Copley is terrific
Verified purchase
Good film. Highly recommend and Sharlto Copley is terrific. Not sure why so many negative reviews. Thought it was very well acted, good script and solid story. Keeps you guessing as to what is going on... has some great plot twists.
Its a creepy film and very dark. If you watch this film and are thinking its going to be a typical Zombie Apocalypse movie then you may be disappointed.

Amazing movie
Verified purchase
Very good, and one heck of a good movie. Storyline is a bit linerar towards the ending, but the beginning, and middle are good.

Would of been better if it was longer, and had a slightly bit better ending, but the main point of the movie is quite good, even though it’s description is a bit misleading.

Still, if you are a prime member or are looking for an actually decent movie in 2019 (which is very rare to find), this one is defiantly worth a watch. You won’t regreat it!

Very average

Group of people with memory loss try to figure out why they are surrounded by dead bodies. An turgid, plodding film that sometimes show scenes of promise, only to be dashed by the slow, disjointed direction. The pace is the real killer. What a shame - the plot and idea are excellent. With a different director this could have been such a good film.
