Dhairya Karwa and Raghav Juyal play two policemen living in two different time periods who find a way to connect with each other to investigate a cold case in the trailer of Dharma Productions-backed Gyaarah Gyaarah.

Dropped by ZEE5 on Wednesday, the two-minute-28-second-long trailer follows the story of two cops — Shaurya Attwal (Dhairya) and Yug Arya (Raghav) — who live in different time periods. One day, Shaurya manages to reach Yug through a walkie-talkie about a case that he’s currently investigating. After his interaction with Yug, Shaurya gets to know that the case remains unsolved even after 30 years. Soon, they figure out that they can only connect with each other through a walkie-talkie at 11:11 pm every night.

The situation surrounding the case keeps on changing as the two cops try to crack it together. Kritika Kamra plays a young police officer named Vamika Rawat, who is also determined to hound out the serial killer in their town.

“An anomaly connects 2 police officers across timelines through a walkie-talkie that comes alive at 11:11 pm every day. As the two help each other solve cases, the reality around them changes forever,” reads the synopsis of the web series in the description of the video on YouTube.

Directed by Umesh Bist, Gyaarah Gyaarah is produced jointly by Sikhya Entertainment and Dharma Productions. The series is the fourth official remake of the Korean show Signal.

Dharma Productions head Karan Johar also shared the trailer on his Instagram handle. ““Can a glitch in time crack the unsolved crimes? Gyaarah Gyaarah premieres 9th August on ZEE5,” he wrote in the caption.

Gyaarah Gyaarah will premiere on ZEE5 on August 9.
