The plot deals with a marine dog named Max. When his handler Kyle (Robbie Amell) is killed in action, Max returns to the states where Kyle's family figure out what to the with the K-9. Max becomes the responsibility of Kyle's younger brother Justin (Josh Higgins). After a rocky start, Justin begins to care for Max and the two become friends. However the two find themselves in the thick of danger when former marine Tyler (Luke Kleintank) returns home and starts trouble for Justin and his family.
Max is not a spectacular film, but nor is it a bad one. While the movie does had issues in storytelling and general filmmaking, it still managed to get its point across by sticking to its concept. Max is a simple family film and though it could have been so much more, this dog film was still a tolerable experience.
