More than likely a blown head gasket. Depends on the situation and how quickly it over heats. Check to make sure your radiator fan is coming on. Could be a bad coolant sensor, fan relay, bad water pump, stuck thermostat....etc. You have to start diagnosing things and ruling them out. It could be many things.
