Narrative:

During flight fumes and smoke developed in first class. Smell was noticed in back cabin also. We were told we were going back to ZZZZ to land. We landed heavy with fire crews waiting. Crews came onboard and checked things out. After hours on plane the lights and emergency lights went out. We used flight attendant flashlights so passenger could at least see something. Probably an hour later they decide to use ramp stands to deplane people.
