ATM: Er Rak Error (retitled later to ATM) is a 2012 Thai language romantic comedy film that became one of Thailand’s all-time top-grossing films shortly after its release. In a bank that forbids fraternization lest one person in the couple be forced out, Sua (Chantavit Dhanasevi) and Jib (Preechaya Pongthananikorn), two career-bound overachievers, have nevertheless been discreetly dating for 5 years.
Frustrated with having to keep their relationship hidden, Sua and Jib decide to get married. However, neither are willing to resign from their jobs.
One day, a software error in one of the bank’s ATMs in Chonburi causes it to malfunction, causing it to double the money it withdraws. Through two poor men, Pued (Thawat Pornrattanaprasert) and Paed (Chalermpol Tikumporntheerawong), word spreads quickly and the ATM draws a large crowd of ecstatic football spectators. ฿130,000 is withdrawn before the machine is shut down.
Jib and Sua make a bet that whoever recovers the money withdrawn from the ATM can remain employed, while the other must resign. Both go to extreme lengths to win. Jib tries to recover the money from the ones that withdrawn thru reasoning, while Sua uses more unorthodox strategies.
