Multiple Sclerosis is a disease that affects the nervous system; the symptoms take many different forms and strikes without warning, sufferers ultimately become the victims of their own body.

In this ad we see a woman break into a home and rig up a series of sinister traps. Each trap is designed to simulate a symptom of Multiple Sclerosis; when the intruder finishes and the homeowner returns, we realise they are both the same person. This demonstrates that 'when you have MS your body becomes your worst enemy'.
