Bernard, an accountant in an upscale jewellery store, suffers from daily psychological abuse by his boss Vendôme. Thanks to his pal Robert, also victim of harassment by this cruel man, Bernard will toy with the consequence of a well-deserved retaliation at the expense of his boss. However, as not everything is perfect in this world, Bernard will also have to experience the sometimes less pleasant after effects of this ruthless act of revenge.
