Penpattanam

Girija is a widow with two school-age daughters. Suhara's husband has been bed-ridden after an accident and his operation requires a huge amount. Santha aka Santhedatthi has to work even in her old age to support her drunkard son and family. Raji lost her parents and lives at the mercy of her sister and sister's husband. Raji is in love with Mani, who is now a plumber but was previously connected to the underworld. Raji's brother-in-law is a policeman opposed to her relationship with Mani. The four women make a living as city cleaners with Kudumbasree in Kozhikode Corporation. Girija and Santhedatthi borrow money from the money lender Unnithan Muthalali.

One day, the four find 3 million rupees left in a waste bin. Initially, they went to hand over the money to police but later decide against it, due to their necessity for money, and give it to Unnithan Muthalali who agrees to pay them a good rate of interest every month. Meanwhile, police find a corpse in the city and find out that the deceased was a hawala (black money) agent. Police, led by Circle Inspector Antony , start investigating the missing money and the clues lead to the four women. Meanwhile, Raji becomes engaged to Mani. The four are interrogated by the police. They deny any involvement and are remanded and sent to sub-jail where Raji is attacked by three women with immoral intentions. Suhara fights them all and saves Raji. They are released on bail with the help of Adv. Maheswari Iyer. Later, Girija asks for the return of the money from Unnithan, who initially refuses and asks Girija to share his bed for the money. Girija informs the others and they together fight Unnithan and trick him to retrieve the money.

Finally, they receive news that a charity will sponsor the operation for Suhara's husband. They hand over the money to the widow of the hawala agent who was murdered. Circle Inspector Antony understands the whole story but finally lets all four go free, since they did not take the money for themselves but handed it over to the ones who really deserve it.
