A new post-apocalyptic Western movie is now available to watch at home

The film has a great cast and a cool setting.

Hailing from New Zealand, the film is set in a world where a biotech virus is transforming humans into zombie-like cannibals that roam the land hunting for fresh meat.

While surviving humans are protected from these creatures in large camps established by the government, the corruption and poor quality of living in these quarantined zones lead many to try to fend for themselves in the wilderness.

The story mainly follows Rory (played by rising star Lily Sullivan - Evil Dead Rise, Monolith), a woman mourning the death of her husband and young daughter two years previously.

Living alone in an isolated cabin with her father-in-law, Otto (Richard Roxburgh - Elvis, Van Helsing), one day, she discovers a severely injured man nearby named Noah (co-writer Lance Giles).

It turns out that Noah's young son has been infected by the virus, leading the father to steal a cure from one of the government camps.

The cure is only effective for 72 hours after infection, so Noah is desperate to get home quickly, which is complicated by his injuries and the sadistic government agent, Logan (Callan Mulvey - The Grey Man, Outlaw King), on his tail.

While Otto wants nothing to do with Noah for fear of trouble, Rory is determined to help the stranger and his sick son.

Co-written and directed by debut feature filmmaker Jordana Stott, on paper, Forgive Us All sounds like a cool blend of a Western movie and a zombie film.

On the one hand, you have horse chases through sun-scorched landscapes. There is also the kindly outlaw, the reluctant hero, the ruthless lawman; all staples of the oater.

But on top of this, there's the flesh-eating zombies and the pondering of who are the true monsters, the zombies or the humans; plot beats you'll often find in horrors such as 28 Days Later, The Walking Dead or the soon-to-be remade Night of the Living Dead.

Forgive Us All doesn't always nail the blend of these two distinct genres, mainly because of an overly dour first hour that drains much of the fun, thrills and vitality necessary for a project like this to work.

Plus, while characters talk about a pandemic sweeping New Zealand and overrun government camps set up to shield humans from the virus, we are mostly confined to Otto and Rory's cabin and the surrounding area, leaving the movie feeling oddly static.

That said, the film roars to life in its final half-hour. This is as Logan and his team of agents (also including a scene-stealing Bree Peters) descend upon our heroes, leading to a tense stand-off and then a series of exciting chase scenes where the lead characters must flee from the law and then the infected.

Perhaps these sequences hit harder because of the extended time spent with the characters in the opening hour. While we can imagine some viewers feeling like the action arrives a little too late, we believe the payoff to the slow burn makes Forgive Us All just about worth seeking out for genre fans.

Forgive Us All is available on digital and DVD now.
