The Guard puts an Irish twist on the fish-out-of-water trope of a sophisticate adrift in the surprisingly complex boonies. Think of the many movies in which a big-city doctor (lawyer or policeman) finds himself in some backwards backwater where all his clever techniques are useless and he must learn the down-home local way of doing things to save the patient (exonerate the accused or catch the bad guy) with a heavy Irish accent and an occasional dose of Gaelic.
In this case, Don Cheadle plays the sophisticated FBI investigator Wendell Everett, dispatched to a small town in Ireland on the trail of international drug dealers who may be making a delivery on the coast there. He is forced by circumstance to partner with the town’s policeman or “guard” Sergeant Gerry Boyle (Brendan Gleason). Boyle is unimpressed with Everett’s work ethic and proceeds with his weekend getaway with two lovely prostitutes from the city, leaving Everett to canvas the town on his own with predictably unproductive results. The two stars provide enough charm and chemistry to carry the relatively lightweight movie on their shoulders.
