Kreng is a vet and is reunited with Fai, his first love, who comes to bail him and his best friend Ohm (her ex-husband) out of jail after drunk driving. But she doesn't remember him from their school days. Fai finds an injured stray dog who is treated by Kreng and they start to interact more. Kreng is sentenced to perform community service and he becomes the volunteer teacher for a group of retirees who are learning how to use the Internet. This puts Kreng and Fai in touch with the older couple - Sompit, a widow who has fallen in love with her classmate Jamrus but her family is planning to move to the US.
