La gran serpiente

One should always be wary of well-dressed, retired-looking middle-aged ladies accompanied by a skittish Dalmatian, like Mathilde Perrin, a plump sixty-three-year-old widow under whose nondescript appearance hides a gun-for-hire from easy trigger and nerves of steel. Skilled and diligent in handling large-caliber weapons, able to slip past the police and wear down her pursuers, this veteran Resistance hero ruthlessly executes the assignments of a mysterious commander when she's not tending her garden outside of Paris. However, her frequent carelessness and the bad character of the once perfectionist Mathilde, which make her increasingly uncontrollable and disturbing, begin to worry the upper echelons, ready to get rid of her before it's too late.
