Is there any fluid in the reservoir? If not then most likely the slave cylinder has been leaking, with the fluid going into the bell housing and exitting via the drain hole, in which case put some more fluid in to get you going, probably also requiring a bleed. See to the slave cylinder as a matter of urgency.
If there's fluid then hopefully the master cylinder needs overhauling or replacing rather than the clutch fork disintegrating or the pressure plate has failed.
