Vanity Bathroom

What is the cause of my bathroom lights and fan not working?
In my master bathroom (attached to the master bedroom) that fires in the bathroom (the bathroom lighting), a fan and an outlet. The fan and lights vanity units are separate. Last night was a storm and lightning, but given the circumstances, I do not think that my problem. Last night I turned off my lights and fan, and when I tried to change again, no work. The departure, I think is connected to the same power source as the lights and the fan running. I tried changing all the switches and out to no avail. For information the switch is in the master bedroom complete, or at least labeled as well, so I guess that covers the Hall main bathroom as well. I suppose I should be related to the switch, since it affects only the light and fan, not the only way out. Can anyone else think of any alternative or suggestion, what to do?
