Following a terrible sandstorm, the pilgrims find a village where everyone has been killed by the evil Grey Gloves Devil, a magician with the power to hypnotise and control anyone who looks into his eyes. While Pigsy lags behind, the others break their journey at another village. A bitter old woman insists Tripitaka is her long-lost son, Su Fung. Meanwhile, Pigsy gets captured and the Grey Gloves Devil looks for a new village to target.

As the pilgrims continue their journey, Monkey sees that a nearby village is being terrorised by swarms of locusts, and they're coming in their direction. Led by the power-hungry Demon Queen Grasshopper, the locusts follow the magic Lake Lok-Nor as it moves from one place to the next. Everywhere they go they bring death and destruction. Can the pilgrims stop them, or will the Queen turn everyone into pigs?

Monkey, Pigsy, Sandy and Tripitaka are on their way to the palace in The Land of Search for Understanding; the king insists on interviewing all pilgrims who pass. Following an argument, Monkey stays behind, and an evil magician turns him invisible. Posing as a Taoist priest, the magician persuades the naïve king to hold a contest between him and reluctant Tripitaka to determine which is better - Taoism or Buddhism. The magician plans to take over the kingdom - will he succeed?

After wandering through endless wilderness, Tripitaka and his starving disciples find themselves in a small town in the middle of nowhere. For two years, ever since her son and his human bride abandoned her, the bloodthirsty demon Kari-Temo Hanja has been appearing at weddings in the town and kidnapping the brides. Monkey goes to seek help from Senju Kannon Bosatsu, the Bodhisattva of endless fulfilment, who was once the demon's master. Meanwhile, Tripitaka decides to pay the demon a visit...
