Manik Babu, a respected Ex-Army officer, with his wife Dipa sojourns in a conurbation near Kolkata. The only son, dayghter-in-law along with the one & only grandson is in abroad. 60-traversed Manik Babu can not accept his son's abroad settlement. It just seems that everyone is keeping his grandson miles apart. Through Skype sometimes they do converse but can not be touch & feel the warmth. So Manik Babu tries to meet up his exasperated passion / wish through his childhood friend, Sen Babu's grandson, Tatai. He narrates various genres of stories to Tatai - even the fairy-tale stories too. Tatai’s all tantrums and fixes are met too. Unfortunately his association with Tatai somehow is not acceptable by Senbabu mentally. Psychologically, he feels that Manik Babu is taking his grandson away from him. There is a cold fight between two grand fathers. San Babu's son's wife and son sometimes enjoy this fight and at times the protest too. In this situation, a circus team emanates in that area. Manik Babu sentries circus with Tatai. Tatai falls in love with the grandeur of circus, especially the circus horse. Then he desires to ride the horse & thereby Manik Babu’s adventure of fulfilling Tatai’s small wish of riding the horse begins…. He faces uncountable obstacles too but remains unblemished & continues his fight. But can Manikababu ultimately fulfill Tatai’s dream & make him ride the horse ? …. Yes yes yes Our story is all about “ Circus er Ghora “ ….
