Paappi Appacha is a 2010 Indian Malayalam-language action-comedy film written and directed by Mamas, marking his directorial debut.

The film stars Dileep and Innocent in lead roles and was released in April 2010 across more than 70 screens in Kerala.

Meanwhile, Annie, with support of Shashankan Muthalali, who is rather inept, yet envious about the apparent prosperity of the Nirappel family, and Annie's colleague Dasan Maash stands against Paappi in Panchayath election, to teach Paappi a lesson about social responsibility.

In the meantime, a businessman Manikkunju comes to the village becoming Mathai's rival, creating problems with the Nirappel men and with the intention to spoil their business.

Later she gets a call from Tony's mother who verbally abuses her, as her son was allegedly brutally assaulted by Paappi.

In a fit of shame and rage, Mathai slaps Paappi and a crack is openly formed in their relation.

Things get worse when the school is mysteriously burned down and Mathai completely disowns Paappi, thinking he is the culprit, also trying to commit patricide in the process.

Shashankan, seeing this as a golden opportunity to rip apart the Nirappel family, steps in and joins side with Mathai, apparently putting Paappi out of the good image.

In a fit of revenge, Paappi tries to shut down Nirappel financial institution now in the hands of Mathai, through a word of mouth on bankruptcy.

However, Mathai, who instantly sees the picture, turns the tables, by publicly lying that it was Paappi who is legally due to settle the financial deals.

Meanwhile, Annie realises her mistake and feels guilty and responsible for making Paappi and Mathai enemies.

But Paappi, out of deep love for his mother, foils the plot by having the land designated as archeologically valuable, without its having such value.

At that night, a drunken duo Mathai and Shashankan, gets attacked by a person with a sword, while walking on the roadside.

Paappi catches him and Shashankan tells that he had some enmity against them but he did not want to kill them and reveals the real person who stabbed Mathai.

His father, Radhakrishnan, who was prosperous than Mathai, had to sell and pledge his land off to the Nirappel family, due to his extravagant lifestyle.
