1999 Ford Escort

I have a 1999 ford escort, checked all the fluids before making a long trip to the airport and back to pick up some family members. On the return trip the car started making a rattling noise when I would put pressure on the gas pedal. With in about twenty miles of home the car started to run hot, I was crossing a bridge at the time so I continued driving, the heater on full blast started blowing cold air. Immediately after exiting the bridge the car shut off. I coasted down the hill and pulled the car off the road, smoke was rolling out from under the hood. I allowed the car to cool then popped the hood. The oil was really low. I left the car sit overnight then returned the next day and changed the oil, air filter, and oil filter. Checked the radiator fluid, still full. Car cranks but wont start.
