Amar's father Brij Bhushan Saxena, who is a capitalist and a wealthy hotelier, wants to give a 5-star hotel to his son as a wedding present. The land for the construction of the hotel incidentally belongs to Bihari. Bihari had previously turned down several offers of selling his land because the house and land are his ancestral property. When Amar requests Bihari, the latter agrees because they go a long way back. However, at the behest of Brij Bhushan, the agreement is drafted in a way that Amar and Brij Bhushan become the sole owners of the land. Bihari, in good faith puts his thumb impression on the agreement and loses his ancestral property. The 5-star hotel gets ready, but on the opening day, some people condemn Bihari's place, which is on the same premises as the 5-star hotel, as a black spot which must be demolished. Amar, who is also convinced with the comments offers Bihari a new house and hotel in return. As Bihari is very sentimental about his hotel and place, he loses his temper and slaps Amar. This sours their relationship. Sudhir, one of the most trusted workers of Brij Bhushan is a corrupt man. He takes the fullest advantage of the misunderstanding between the two friends and takes Brij Bhushan into his confidence, demolishes Bihari's place and hotel by a bulldozer and claims that Amar, in a state of inebriation had ordered its demolition. Amar believes Sudhir and pleads for forgiveness from Bihari, offering to rebuild the structure for him. However Bihari does not relent and declares that he will himself build a chain of hotels and outshine Amar one day. Bihar is given shelter by his most trusted friend Bhimji Nanji Premji Batliwala, a la wyer by profession. In the meantime, Amar learns that Sudhir is a traitor and throws him out of his house.
