[1] Its popularity spawned a sequel, titled Battlefield Heroes, which debuted in 2011, and takes place in the subsequent Silla-Tang invasion of Goguryeo.

As the court disintegrates into infighting and name-calling between the royalist faction and the disgruntled nobles, the Baekje king, Uija, calls for general Gyebaek, a loyal, able and honest general who accepts the responsibility of riding out to meet the 50,000 Silla troops, who outnumber his army 10 to 1.

Before leaving to battle, Gyebaek, who realizes the odds and knows he will not be able to return alive, kills his family by his own hand, afraid of what may happen to them if they were to be captured.

The attacks, which are an attempt to learn what Gyebaek's mysterious plans are and to lure the Baekje army into open battle, fail.

It is a wet and rainy day, and the Silla army fire balls of clay at the defenders with catapults, which weigh down the tiring Baekje troops and force them to take off their armor.

As Gyebaek falls after being hit by a volley of arrows, he recalls his family, who had in actuality wanted to live, and did not see him as a hero of the country, but only as a bad father and husband.
