This movie was produces and directed by the Ramsays -the hini version of Hammer House Of Horror.Later on Keshu Ramsay would leave his last name, be known as just Keshu and would make approx 15 films with Akshay Kumar like the Khiladi series. Saboot is one of their earlier movies and actually one of their best.The story revolves around 2 sisters Vidya Sinha (the actress who was seen in classics like Chhoti Si Baat, Rajnigandga and Swayamvar) and Kaajal Kiran (who was seen in Hum Kisise Kum Nahin with the song Kya Huwa Tera Vaada, who was married to Punneet Issar -the actor who beatup Amitabh Bachchan during the filming of Manmohan Desai's Coolie when Amitabh almost died). Their father is brutallu killed so is the husband of Vidya played by Vinod Mehra. Then mysteriously one by one the killers start dying. Suspected is that the ghost of the father is taking revenge. A friend of Vinod played by Navin Nischal - a police inspector) is given the task to solve the case. In the meantime he falls in love with kaajal Kiran. This is ne of the last movies in which you can hear the first Bappi Lahri. That is before the Himmatwala period started and he composed sensible songs. One of my alltime Kishore-Asha duets is in this movie "Jeena Bhi Koi Jeena Hai, Jabtak Tera Saath Nahin".
