This is primarily a movie about escaltion, and skillfully shows how small things can eget out of hand when people refuse to let things go. In this case it's Brian cox's character seeking an apology after young thugs kill his dog red.
I won't go into too much detail, as amazon themselves provide the best synopsis for this, nor would I want to ruin the film by spelling out the plot. I guess people who have read the book may already know but I am yet to read a Jack ketchum novel (something I will soon remedy). What I will say is that this is a damned good little movie. Don't watch expecting another death wish, brave one or death sentence as this is a far more sedate and character driven movie with an excellent central performance from brian cox. While nontheless gripping, it is rather anti-violence, showing how seemingly trivial matters can soon get out of hand. No extras to speak of but the print is fine and well worth watching.
