Garrison is principally the story of two army officers, Sergeant Daniel McManus (Kerry Valderrama, also the film's writer and director) and Staff Sergeant Nathan Cross (James Barnes), two soldiers facing different but no less difficult issues in readjusting to life back home.
Sgt. McManus has faced trauma whilst stationed in the war zone, but is doing his best to move forward. However, his work in training the garrison's new recruits and existing soldiers is placing strain on his marriage to wife Andrea (Elizabeth Ingalls). Meanwhile, Ssg. Cross is showing erratic behaviour and having disturbing accusations made towards him about his rapidly disintegrating marriage. When Ssg. Cross goes AWOL from the garrison, Sgt. McManus faces a race against time to find the increasingly unstable officer before the Military Police do, as arrest would mean the end of Ssg. Cross' military career.
Garrison sets out with an intriguing premise, but ultimately fails to overcome it's underwritten script and very low budget. The film's presentation will undoubtedly put many viewers off, with it's drab locations, poor lighting and off-kilter camera-work dragging down many of the scenes. Although the script fails to create any real tension or drama, it does at least attempt to portray the damaged psyches of soldiers returning home from war without being too preachy or overbearing. The supporting characters are also fairly engaging, with Ssg. Xavier 'The Machine' Rivera (Jason Cox) being a standout. However, the characters are given very little to do throughout the movie, with only the dramatic final act letting them (and indeed the actors) spring into life.
However, Garrison is by no means a bad film. It has an earnest quality and it is apparent that the filmmakers and cast were trying hard to make a good movie, it's just that not everyone involved had the required skills to overcome it's low budget. In it's favour, Garrison is at least decently acted by a cast of virtual unknowns and the basic story line is a strong one. Unfortunately, although Valderrama is not without some talent, his writing and directing skills in Garrison are not quite strong enough to raise this movie from the annals of mediocrity.
