August 1 is a 1988 Indian Malayalam language action thriller spy film directed by Sibi Malayil, written by S. N. Swamy, starring Mammootty, Sukumaran and Captain Raju.

As a young turk with a clean image, KGR overshadows Kazhuthumuttam Vasudevan Pillai, who is another strong aspirant for CM's chair.

Just after the meeting, Kazhuthumuttam joins with Eranjoly Aboobakkar and Mathai Thomas Pappachan at a hotel room to plan the next move.

Vishwam contacts Muniyandi Thevar, a Malaysian-based businessman and smuggler in Madras, who introduces him to a professional assassin Nicholas, but after the payment of the amount, Kazhuthumuttam feels cheated again as he has been denied the CM's post.

In a state of intoxication, Kazhuthumuttam calls up Gopu, a journalist and spits out the information that KGR will be assassinated shortly, but without committing his identity.

Even though the caller does not give his name, Gopu identifies him as Kazhuthumuttam and therefore passes the information to his friend DYSP Perumal who is an honest and sharp police officer posted in the state Crime Branch.

On the day of 15 August, KGR is checking the guard of honour, Perumal waits eagerly with all police facilities to grab Nicholas.

While scanning the CCTV footages, Perumal finds Nicholas among the cops disguised in a police uniform, in the line for the guard of honour.
