Senior - Official Trailer

The newest enrollee at a convent boarding school, the introverted Mon (Jannine Weigel) becomes the laughing stock when her classmates catch her sniffing at various objects all the time. Perceiving her as a weirdo, what they do not know is that Mon actually possesses a paranormal power that allows her to smell the presence of spirits. One night in the girls’ toilet, Mon encounters a mysterious ghostly being, who calls himself Senior (Pongsakorn Tosuwan), and is roped into his investigation of a brutal murder that happened 50 years ago. Senior is invisible to everyone including Mon. Along the way, the unlikely detective duo runs into both human and supernatural forces that attempt to obstruct them from the truth, no matter what it takes.

On the other hand, who is the mysterious Senior? Will Mon live to find out?
