Jom is an architect responsible for the renovation of a historic house alongside the Ping River. There he discovers a wooden chest packed with old drawings, drawings that look strangely familiar. The contents are intriguing. However, Jom doesn't have time to concern himself with them; he must take a trip back to Bangkok to see his love. For years, Jom has been counting the days till his boyfriend would return from his far away studies, only to find him engaged to someone else.

Heartbroken, Jom comes to a place of acceptance as he runs his car into the river. In the cold darkness, Jom catches the sweet scent of fresh frangipani flowers coming from the stream and in the distance, he can make out a deep, gentle voice pronouncing clearly, "Pho Jom."

Jom will find himself waking up in 1920s Chiang Mai.
