An ex-special services veteran, down on his luck and desperate for work, takes a job as a security guard at a run-down mall in a rough area of town. On his first night on the job, he opens the door to a distraught and desperate young girl who has fled the hijacking of a Police motorcade that was transporting her to testify as a witness in a trial. Hot on her heels is the psychopathic hijacker and his team of henchmen, who will stop at nothing to extract and eliminate the witness.
I haven't seen someone do the "Die Hard In an X" thing in a way that I enjoyed in a while, so Security was actually a pleasant surprise. Sure it's derivative, but a good time is a good time.
Final rating: - I liked it. Would personally recommend you give it a go.
