What have you tried so far? Check the belts first to see if one is broken but if the car won't go into gear, it's likely a transmission problem. You didn't say whether it's an automatic or manual transmission so to cover all the possibilities, the most common cause would be a cracked flex plate for an automatic or a broken shaft or gear in a manual transmission or the clutch disc fell apart. A broken axle shaft is less expensive to repair but you would typically have a horrendous banging and vibration, depending on which joint on which end of the shaft broke. There would also likely be a small puddle of fluid under the front of the car.
If you can't see anything obvious, have the car towed to a mechanic who can visually inspect it.
