Jung Chae-yeon and Jung Gun-ju to Star in TVING Horror Series M: Reboot
The original 1994 drama, which starred Shim Eun-ha and featured an iconic green-eyed protagonist, caused a sensation with its groundbreaking genre, eerie atmosphere, and bold themes that included sounding a heavy social alarm on abortion. The upcoming reboot aims to inherit the chilling atmosphere of the original while incorporating a fresh sensibility for a new generation of viewers.
Challenging a Triple Role and Detective Investigation
In M: Reboot, Jung Chae-yeon takes on her first triple role since her acting debut. She portrays Marie, a promising high school ballerina attending a preparatory or arts high school who grows up under a strict politician father and an overly attached mother; Jenny, a veiled genius surgeon from the United States with mysterious intentions and a past; and M,
the enigmatic personality that awakens within Marie.
Marie’s life is upended when recurring nightmares disrupt her preparations for an audition at a top-tier global ballet school, paving the way for the mysterious personality to take hold. Alongside these developments, actor Jung Gun-ju steps into his first detective role as Ji-seok, an ace investigator trusted by his colleagues for his quick judgment and tenacious skills. Ji-seok becomes entangled in a bizarre case as he pursues the truth behind mysterious incidents surrounding Jenny, confronting memories from a decade ago whenever an unidentified green afterimage or light appears.
