Lacuna

Shen Wei and Tong Xin awaken together in a bed inside a furniture store, both drunk and with no memory of how they ended up there or who the other person is. They quickly realize they cannot identify each other and decide to part ways to avoid confusion. The moment sets the tone for a chaotic night that has spilled into their lives. They separate to search for clues about the previous evening.

Wei, Xin, and Meng Qiqi appear in Internet videos filmed the night before, creating a public scramble to piece together what happened. The clips reveal their notoriety and raise questions about their actions and relationships. Wei and Xin start trying to reconstruct memories that remain murky. The search for truth begins as they try to piece together last night's events.

Xin cannot account for three hundred thousand dollars intended as a bribe from her boss to Qiqi to end the director's relationship with the actress and to keep her quiet. The unresolved money becomes a persistent thread driving their investigation. Wei and Xin start suspecting everyone involved in their night, hoping a clue will emerge. The mystery deepens as they try to reconstruct events.

They receive a call from the police about a missing pet and are told they must both come to claim it. This summons nudges them to coordinate and start piecing together the night's events. The call marks the first step toward a shared memory they are trying to reconstruct. Their decision to meet the police pulls them into a joint investigation.

A bag claim token leads them to an upmarket bar where they uncover Qiqi's wallet. The staff greet them by name and treat them as VIP after they reportedly spend around 90,000. The bar sequence escalates their status and intensifies the mystery of what happened that night. It also reveals how much trouble their actions have generated already.

They visit an unusual police station and learn their pet is an alpaca that ate apples from a store. The sergeant clues them in that Xin claimed they must take the animal to her boss or the 300k would be useless. The absurd detail underscores the absurdity of their situation. The alpaca becomes a central proof point in their night.

Xin remembers that Qiqi refused the money, which shifts blame and clarifies some motives. The alpaca is introduced into the director's Nativity scene, manipulating the film's production as part of the night's chaos. The consequences ripple through their plan to handle the bribe and the actress's secret.

Wei and Xin receive a text that sends them to another club where they meet Pupi, the club's lead singer, and Choize. The messages weave through the night and widen their circle of complicating factors. The atmosphere shifts from investigation to pursuit of more clues. The club becomes a crossroads for their unraveling memories.

Choize's thugs drag them into a car and interrogate them to locate Maria, who left with them the night before. The dynamic grows tenser as the truth remains scrambled. Xin discovers the frog they filmed licking is central to the mystery and the fear it inspires. The chase threads tighten around a single, peculiar clue.

Xin is held hostage while Wei returns to her apartment to recover the frog. The personal danger amplifies their need to remember the night and recover what was taken. Wei's dangerous mission intertwines with Xin's memory and fear, highlighting their shared vulnerability. The frog becomes a keystone in resolving the sequence of events.

The pair recall visiting a construction-site apartment full of artistically sculpted furniture. Wei cheerfully decorates the space using building materials to lift Xin's spirits after the breakup and the chaos. The materialized memories become central visuals that anchor their night. They search for the missing money amongst the chaotic art.

In a drive-in cinema, they locate Wei's car and, in the boot, Wei's missing friend White Hair and Qiqi, accidentally locked in. The discovery stitches together parts of the night and assigns new urgency to their search. The moment confirms that clues are scattered across locations. They press on to resolve the mystery of the money.

White Hair hands them another baggage claim token and they sprint to collect it. They finally uncover Xin's bag containing $180,000, the core financial thread of the night's chaos. The revelation shifts the narrative toward closure as the sum seems ready to change hands one last time. The tension eases as the money is recovered.

Wei and Xin exchange phone numbers, signaling a shift from confusion to tentative partnership. The film closes with a montage showing the trio wandering into the furniture store, through an alley, and into an unlocked door, hinting at what slipped past them and what might still be unresolved. The memory of last night lingers as they step into the future together.
