Episode 5 of "Interior Chinatown" kicks off with Willis confiding his suspicions to Lana, whispering that Uncle Wong might be harboring secrets and hinting that his brother’s entanglement stemmed from uncovering them. Driven by curiosity, Lana decides to visit Willis’ parents, hoping to gain access to Uncle Wong’s mysterious room.
Elsewhere, Detective Turner confides in Lana, expressing his growing conviction that cases seem to resolve themselves as if by magic. Lana dismisses his notion, trying to rally him by affirming that he and Detective Green form an unbeatable duo. Their conversation unfolds amidst the chaos of a new case—a bombing that Turner and Green are urgently trying to crack.
Later, Lana arrives at the restaurant to find the family immersed in a lively dinner, joined by the jovial presence of Fatty and the enigmatic Uncle Wong. Amidst a karaoke session filled with laughter and melodies, Willis catches snippets of Uncle Wong’s hushed warnings, telling someone not to involve the police—a statement that immediately strikes Willis as suspicious.
Post-dinner, Lana hatches a plan, taking Willis and Fatty to a club with the intention of getting Fatty sufficiently inebriated to steal Uncle Wong’s keys. However, fate had other plans, and the trio awakens the next morning, still in the house, with the plan in tatters.
As the day progresses and Willis lends a hand at the restaurant, he stumbles upon Uncle Wong’s keys while Fatty is engrossed in running the bustling establishment. Seizing the fleeting moment, Willis slips into Uncle Wong’s room and uncovers bullets and his brother’s pager, hidden away like treacherous secrets.
At that precise moment, Uncle Wong returns, catching Willis red-handed in his room. In a desperate bid for freedom, Willis narrowly escapes through a labyrinth of tunnels that are interconnected with Wong’s room, uncovering a hidden truth—Chinatown is intertwined with these clandestine underground passageways. Wong relentlessly pursues him through the winding tunnels, but Willis, with a mix of ingenuity and luck, manages to evade capture.
Meanwhile, Detective Turner becomes increasingly cognizant of the surreal, fictionalized fabric of their world. Assigned to neutralize the bomb, he realizes with astonishment that his theory about cases solving themselves holds true—despite not severing any wires, the countdown mysteriously halts on its own, as if controlled by unseen forces.
