Is the smell coming from the plug at the wall ? If so I would shut down the circuit breaker for that room, and replace the plug. It is easy . Go to a hardware store. get a replacement plug. After you shut down the circuit breaker for that room, test the plug to make sure it has no juice , use a lamp or somthing like that. then unscrew the plug. you will see a white wire connected (neutral) and either a red or black (hot) . Just replace as it was, if there are multiple white, or multiple red or black just remember how it is connected and replace.. if your not sure then get someone who dose remodeling, or general contracting to help you, or you could call an electrician
