Narrative:

Normal takeoff from ZZZ. Shortly after takeoff, flight attendant called on interphone to tell us of smoke in the cabin. Captain made quick decision to return to the airport and told flight attendant such. We declared an emergency and were vectored to runway 24 for landing. Right hydraulic system was lost and rudder control went to manual. On downwind to runway 24, we began to smell the smoke as well and it increased as we were on final. It was a strong smelling smoke that burned at your eyes. We had to lower the gear manually on final due to hydraulic loss. Normal landing and touchdown under maximum weight. We turned off at taxiway lima and stopped for equipment to evaluate us. We were told that they saw nothing unusual except that the gears doors were dragging. We called maintenance and had them come inspect the aircraft further, pin the gear doors up, and tow us to a gate. We had a total of 39 souls on board (sob's), all of which switched aircraft with us and continued trip uneventfully. Total air time was 9 mins. Callback conversation with reporter revealed the following information: the reporter stated the cause of the smoke and mist was hydraulic fluid spraying from the nose gear retract pressure line aft of the pressure bulkhead. The reporter said the smoke was strong and acrid with eye burning sensation. The reporter stated the location of the line failure put it right under the most forward part of the passenger cabin.
