Plot: A police officer is in a race against time when assigned to a call involving a kidnapping.

Most films that I'm seeing at this year's Leeds International Film Festival are based purely on the buzz they've been getting. This one has had some pretty positive ones.

This particular film hits the ground running straight away and does let up. I also noticed that we were going back to in one location for the entire duration. That pleased me, as when a film that is in one location works, it works really well. I'm a big fan of these types of films, so this was right up my street.

I was seeing a lot of structure similarities to the Tom Hardy thriller Locke. It was painting a picture beautifully of what was happening off-screen.

Some cool twists, a little bit of black-comedy as well as a gripping finale later and I felt pretty satisfied afterwards.

With 99% of the performances being voice-work, it was down to Jakob Cedergren to give us the presence that can carry this entire film. He passed with flying colours as he made great use of his characters back-story and showed a very troubled person just trying to help someone whilst putting the law into his own hands in the process.

There are lots of things that make this film work. With there being very little to work with in terms camerawork moving locations, a lot of other aspects have to be of a high-standard.

As mentioned before, the phone-call scenes gave us such a clear image in our heads of how it would've looked on screen. It is quite something to make us feel invested in characters that we never see.

That and the strongly developed back-story given to the main character gives us more aspects of the story to explore.

All of that time and effort given to these characters gave us quite the emotional finale.

It's not quite up there with similar films such as Phonebooth, Buried or Locke, but it's very close.

But for a directorial debut, Gustav Moller and his team have given us a strong thriller that could easily rival the best of the decade within its genre.

The tension is great, Cedergren does as a top performance and the strong character development for me was the most important cog to keep this wheel moving.

Rating: 8/10
