Modern night market couple Gu Yan and Su Wan cross over to an ancient battlefield, cart, stand, and all, on a stormy night. The city is full of wounded soldiers, out of grain for three days, and besieged by one hundred thousand barbarians. Relying on their grill, freezer, and seasoning cart, starting from exchanging a table of barbecue for life, barbecue skewers, dried meat, meat coupons, night market, chili smoke, and sowing discord—using modern barbecue skills and business brains, they step by step sustain one hundred thousand soldiers and civilians. Huo Xiao and Lao Zhou go from suspicion to entrusting their lives to each other. With grain exhausted and reinforcements cut off, the couple use a table of "Hongmen Barbecue" to outwit the barbarian king and his son with chili smoke arrays, fake intelligence, and interlocking fire pits, finally staking the life of an entire city to grill a desperate counterattack.
