Neon (
Rachanun Mahawan), a night-shift worker at a 24-hour laundromat, finds excitement in her routine through her interactions with Night (
Korapat Kirdpan), a regular customer and her favorite mystery novelist. Following a series of encounters that bring them closer, Night suddenly stops visiting the shop. Prompted by concern, Neon locates Night at his apartment, where she unexpectedly discovers a suitcase of cash. Overwhelmed by temptation, she takes the money and decides to cut off contact with him. However, she soon learns that the money was stolen by Night from a mafia syndicate. When Night attempts to retrieve the funds, they discover the suitcase is missing from Neon’s hands. The two form a reluctant alliance to find the real thief using laundromat records that list five suspects: Judo (
Naravit Lertratkosum), a college student; P'Chompoo (
Tachakorn Boonlupyanun), Night's landlord; Momay (
Ploynira Hiruntaveesin), a karaoke hostess; and a rock couple, Nick (Patara Eksangkul) and Smile (
Jennie Panhan). Neon and Night must analyze their habits and approach them one by one to get the money back. The investigation eventually reveals P'Chompoo as the culprit. Driven by years of living from hand to mouth, she seized the opportunity to escape her financial struggles and secure a more comfortable life. Unfortunately, she has already exhausted the funds, having invested half the total amount. Faced with the mounting pressure of the syndicate's arrival, the duo and the suspects unite to design an intricate scheme, leading them to deceive the mafia and resolve the crisis through their collective efforts. == Cast and characters ==
