Luke Wright (Jason Statham) is washed up former cop who also shares a sad & horrifying relationship with the Russian mob. Years ago he refused to take a dive in an underground mixed martial arts fight and in order to teach him a lesson the Russian mafia killed his wife and child and promised to watch over him and kill anyone he befriends. So Luke walks around New York in a perpetually bad trying to avoid any personal connections until a ten year old Chinese girl, Mei (Catherine Chan) comes his way. Mei has memorised a huge number which holds the key to a lot of money for the Chinese Triads. Soon enough other than the triads, corrupts cops, a corrupt mayor and the Russian mafia want their hands on the girl too; with Luke Wright in their way none of it is going to be an easy task.
Stathams fight sequences a utterly brutal and enjoyable, since he rarely holds back from going full throttle. The aim is simply to seriously maim or kill the opponent in every fight which is there resulting in shorter yet more bloody fights.
I guess the other thing that works well for Safe is the pacing of the film; the fact that it never really slows down and is filled with moments of wit or dark humour evens out the tension. Its unapologetically cheesy and shallow in terms of characterisation and plot at times but its primarily a showcase for the awesome fights and thats what it does best.
