Isabelle is the young ingénue assistant, while Christine is the older woman, a senior executive in a multinational company doing deals around the world. At first they are friendly. Christine, the able executive, is happy to pass the grunt work along to the up-and-coming Isabelle as she learns the ropes. But when Christine starts to take credit for Isabelle's ideas, and a fellow worker bee begins to fuel Isabelle's growing doubts about Christine's duplicitous "all-for-one" attitude, the ground is prepared for all out war. And all out war certainly ensues.
