After a long wait, the trailer of Jayasurya's Anveshanam has finally dropped. Judging by the footage, all signs point to an intriguing medical investigation thriller. An incident revolving around a child and a family make up the film's core plot. The main characters are played by Jayasurya and Shruti Ramachandran.

In the trailer, we also get a glimpse of the mysterious character played by Vijay Babu. Leona Lishoy and Nandhu seem to be playing police investigators in charge of the case, while Lal and Lena essay the doctors at a private hospital, which is the film's principal setting.

Directed by Lilli-fame Prasobh Vijayan, the film reportedly takes place over a single night.

Lucifer-fame Sujith Vaassudev seems to have lent the film the necessary amount of chills through his lighting with ample support from Jakes Bejoy's thrilling score. E4 Entertainment is bringing the film to cinemas on January 31.
