The Liability is about a young man named Adam (Jack O'Connell) and the price he pays for youthful foolishness. After completely wrecking his mother's boyfriend Peter's (Peter Mullan) Mercedes, the man requires Adam to repay him. For starters, he has him do lawn work and other menial tasks, but then he decides to send him out to assist a "business associate" named Roy (Tim Roth). Initially, Adam doesn't know that Roy is a hit man for Peter, but after recently seeing some evidence of drug and human trafficking on Peter's laptop, nothing surprises Adam. Roy takes him on an interesting ride and Adam starts to get the hang of things, not quite realizing that Peter knows Adam has become aware of his illegal activities and that he, himself, is Roy's final target.

As the odd day progresses, one of Roy's kills is interrupted by an enigmatic young woman (Talulah Riley) walking in the woods, a potential witness. But neither Roy nor Adam was prepared for this woman as she not only evades them, but steals their car and the evidence of the murder that was in progress when she arrived. As Roy and Adam go on a mad dash to retrieve the evidence and silence the girl, they discover she is far more than they first imagined and is on a mission all her own. As the movie draws to a close, it's anyone's bet who will live and who will die.

I was initially intrigued by the premise of The Liability and I love watching Tim Roth, so that promised to be a bonus. However, The Liability is fairly lackluster and dull, despite what should be an exciting plotline. The acting is competent and Peter Mullan portrays an absolutely heinous villain, but I just didn't really enjoy the film all that much. I suppose I didn't find myself invested too much in the characters, whether it was because they weren't particularly likeable or simply flawed, but not more interesting for it. I just wasn't riveted by the film. Special features include a making of featurette with some interviews with the cast and some trailers.

All in all, I can't really even recommend The Liability unless you are simply a huge Tim Roth fan. It's not just that exciting or interesting and there are better films out there.
