Undertone Official Trailer (2026)

First-time director Ian Tuason puts a new spin on psychological horror with The Undertone, starring Nina Kiri as Evy. She’s a no-nonsense podcaster who plays skeptic to her co-host Justin (Kris Holden-Ried), but things get personal when she moves home to care for her dying mother—and starts getting eerie sound recordings from a couple convinced their house is haunted. What really sets this film apart is that Evy is the only one we ever see on screen, while voices from the rest of the cast echo in from phones and speakers, cranking up the paranoia and tension. Shot in the Toronto neighborhood of Rexdale, The Undertone leans hard into sound design and atmosphere over flashy effects, keeping you on edge for its tight 85-minute runtime. The film picked up the gold audience award at Fantasia before A24 snapped up distribution rights, so expect a slow-burn ghost story that gets under your skin and lingers long after the credits roll.
