Virata Parva covers the tensest single stretch of the exile: the condition of the Pandavas' banishment requires that their final year pass entirely unrecognized, on pain of the whole thirteen years restarting from the beginning, and the book follows all five brothers and Draupadi as they take on disguised roles at the court of King Virata. Yudhishthira poses as a courtier skilled in dice and counsel, Bhima as a palace cook renowned for his strength, Arjuna, under a curse from an earlier encounter, spends the year as a eunuch dance and music teacher to the princess, Nakula and Sahadeva take roles managing horses and cattle, and Draupadi serves as an attendant to the queen while fending off the unwanted advances of the queen's brother, the army commander Kichaka, whose eventual assault on her provokes Bhima into killing him in secret, nearly exposing them all.
The book's climax arrives when a rival kingdom, the Kauravas among them, raids Virata's cattle, forcing Arjuna to reveal his warrior skill in defense of the kingdom just as the year of concealment ends, the disguise falling away in a dramatic battlefield unmasking rather than a quiet expiration of the sentence. Duryodhana, suspecting the Pandavas may be hiding at Matsya, deliberately times the cattle raid to test whether their year is truly complete, so the raid itself functions within the story as much as a detection scheme as a military strike.
