A plunger is only going to help if the plug is in the toilet itself. It may be further down the drain. You could have tree roots in the line. A simple fix that may help is this. Get a 5 gallon bucket and fill it with water. Pour it in the bowl as fast as it will take it. Bring the water level in the bowl up to the bottom of the rim and keep pouring until all 5 gallons is used. This is a much greater volume of water that the toilet normally send down the drain and may flush out a partial clog. It will not hurt anything if it does not help.
Get a plummer in or buy a plunger :)
The best thing to do is to use a plunger first. Plungers will take care of most clogged drains but if you have a serious clog try using a snake.
