Haans-Vimān, an aircraft, part bird, part machine, is created by Sage Vallabha in ancient times. The sage records, its creation and piloting techniques in a manuscript. The manuscript survives the apocalypse.
The story fast forwards to the twentieth century. The sage returns the manuscript to its rightful heir Abhiraat. Meanwhile a group of people, calling themselves the ‘society of flying crafts’ (SFC), are after this manuscript.
