Trùm Sò is a satirical period comedy set in the remote Jellyfish Village, where poverty is widespread—except for one man. Trùm Sò is absurdly rich yet notoriously stingy, obsessed with money to the point of denying himself even the simplest pleasures. His tightly controlled world collapses when a large amount of his gold suddenly disappears. Driven by greed rather than reason, he is pulled into a chaotic heist alongside two unlikely allies: Thị Hến, a sharp-witted widow, and Tôm Hùm, a flamboyant drifter.
