Kadathanadan Ambadi is a 1990 Indian Malayalam-language sword and sorcery film directed by Priyadarshan and written by Cochin Haneefa. It is a sequel to the 1964 film Thacholi Othenan and the 1970 film Othenente Makan. The film star Mohanlal in the title role, along with Prem Nazir, Swapna, and Raadhu. Kadathanadan Ambadi was in production since 1985 and was stalled due to financial crisis faced by the producer Sajan Vargeese. A few shots from Thacholi Othenan was shown in this film. Kadathanadan Ambadi was released after the death of Prem Nazir.
The movie is based on Kerala's traditional Vadakkanpattu (The Northern Ballard Folklore). The fictional story is about Kadathanadan Ambadi (Mohanlal) who wants to avenge his father - Thacholi Manikoth Othenan Kuruppu's death and retrieve the sacred sword Bhadravaal and Sacred Thread, which were missing since the death of Thacholi Othenan.
Kadathanadan Ambadi, along with his Mentor-Martial arts Guru sets out investigating the mysterious disappearance of the sword. They suspect a Muslim Manager of their household who went missing since that day. While searching, they reached a kingdom, whose ruler was a mysterious Black Magician called Kowliya. The Magician Ruler Kowliya used to send his eagle to search for each's day beautiful lady, to be sacrificed each day for strengthening the King. In that process, the eagle settled on a house whose lady's marriage was fixed on that day. The soldiers dragged the girl and brought her to the sacrifice pit, only to be saved by Ambadi, who killed the King.
It was later found that, the girl and her brother were sons of .[clarification needed] Moyideen narrates the story, who within the Thacholi family plotted to stage a coup and get hold of the sword, making the thief later sold as a slave to Tulunad's King. The King also holds the key to a secret magical cave where the sword is kept. Ambadi sets out to Tulunadu, where he lures the princess and gets to know the whereabouts of the key. Ambadi fights against the King and his soldiers and grabs the key from his necklace and proceeds to the Magical Cave with his Guru, Payyappilly Chanthu. He had to fight against the Demoness (Nagayakshi) who guards the sword as well as a Water Demoness.
After getting back the Sacred Sword - "Bhadravaal", he returns to Kadathanadu with his Guru, Payyappilly Chanthu. But they were not aware of the fact that his father's sister - Unichala (Sukumaari), her two children (Ganesh Kumar and an unknown actress) and Moosakkuutti (Srinivasan) were captured by Kathiroor Chandrappan (Kochin Haneefa). Payyappilly Chanthu's (Prem Nazeer) daughter Kunjilakshmi feels betrayed as she knew that Ambadi was not alone, but with a Princess.
