Sone Pe Suhaaga released worldwide on 26 August 1988, directly clashing with Biwi Ho To Aisi starring Rekha.
The film begins with a sincere Constable, Viswanath, living with his wife, Usha, elder son, Vijay, and twin boys.
At that juncture, a spiteful & covetous Inspector, Tejaa, connives by killing Viswanath and incriminates Bashir Ahmed.
During that plight, she decides to immerse the corpse in the river but, unfortunately, throws the living child—moreover, Tejaa re-attacks, which Vijay also detaches.
Hence, Tejaa falsifies the judiciary in cahoots with Justice Nyaychand Rastogi and purports an orphan, Ravi, as Joginder, who is Usha's surviving twin son.
Prior, his close friend Dr. Premnath broke his kidney racket of Tejaa on the day of his nuptial with Advocate Shraddha.
In tandem, Tejaa backstabs Nyaychand Rastogi, who divulges the fact as his death statement, and the judiciary frees Ravi.
