A dual-timeline mystery and queer summer romance as two boys set out on a sun-soaked adventure to uncover how someone else's love story really ends. Two love stories. Two time periods. One mystery. Fifteen-year-old Noah lives with his dad in New York but is spending the summer with his mum in California. An indoor person and RuPaul fanatic, Noah is miserable in the west coast sun - until he meets Tomo, a surfer who works part time in a vintage store. Tomo hands Noah a pair of old school-style notebooks from the 1980s, filled with steamy diary entries by its teenaged owner, Diego. Noah reads about Diego playing footsie in class with closeted surfer Casey, until one day their flirtation becomes something more.

Noah is enthralled, but the second notebook ends on a cliffhanger, leaving him and Tomo with no idea what happened to Diego and Casey. As they set off to find out, the two boys discover a romance of their own, but can Noah keep from sabotaging the first good thing in his life?.
