Synopsis Wan (Worapong Walor) is a devoted fanboy of the emerging actor Nine (Supamongkon Wongwisut). While in his final semester of university studying public relations, he also works as a freelance photographer, capturing actors at fan events.

During the line up event announcing Nine's new series, The Deep Between Us, Wan finds a spot to unbox his merch in a restricted area, where he gets caught by Nine's sharp-tongued co-star Third (Thanaphum Sestasittikul). Wan is accused of being a stalker fan and tries to flee, but accidentally enters the actors' dressing room. Escorted out by security, his friend Jay (Nattanan Chindanon) comes to his rescue.

Wan learns his mother (Sujira Arunpipat) has fallen for a voice phishing scam, putting the family into financial debt. Wan finds himself entering the entertainment industry out of necessity. Despite his lack of acting experience, Wan is unexpectedly cast in a supporting role for The Deep Between Us after a fiery improvised audition opposite Third.

Third is left unimpressed when Wan shows up to his first day of acting lessons late and unprepared. Although they initially clash, the two gradually form a deeper connection as they see each other in a new light. Wan begins to discover the reality behind the scenes and must use every skill he possesses to survive in this industry.
