[1] The series stars Vivek Oberoi, Aftab Shivdasani and Riteish Deshmukh in principal roles.

[2][3] Masti revolves around three bachelors, Meet (Vivek Oberoi), Prem (Aftab Shivdasani) and Amar (Riteish Deshmukh).

Prem marries Geeta (Tara Sharma) who is overly religious and thus their sex life suffers.

Amar marries Bindiya (Genelia D'Souza) who is dominating and lives with her mother (Archana Puran Singh).

The men set their sights on other women but eventually realise they have all been seeing the same girl, Monica (Lara Dutta).

To not be accused, they try to hide her body, interrupted by police officer Sikander (Ajay Devgan) who begins to suspect, and then starts following, them.

Next morning, a mysterious man finds them and reveals that he killed Monica and demands ransom to cover the crime.

Three friends – Meet (Vivek Oberoi), Prem (Aftab Shivdasani) and Amar (Riteish Deshmukh), who are married and don't like their wives: Meet thinks his wife Unatti (Karishma Tanna) is having an affair with her boss, Prem doesn't like it when his wife Tulsi (Manjari Fadnis) doesn't spend quality time with him and Amar hates his marital life because his wife Mamta (Sonalee Kulkarni) is more concerned about their son, Pappu.

This all due to the fear of a Principal Roberts (Pradeep Rawat), who hangs people naked on a tree if they disagree with his rules.

The principal chases them down thinking they had sex with Marlow, Mary and Rose, but they get away as their wives come to spend time with them.

It's the last day, and the vengeful principal has put pills inside the soup which attract people to the ones they love.

Shortly later, a doctor comes and informs the principal that he is no more impotent since the blood now properly flows all over his body due to the pressure generated while hanging on the bar.

Amar's mother-in-law wants her late husband to be reborn and on the order of a fraud baba (fake spiritual leader) she has stopped her daughter from having any physical relations with Amar for over six months to achieve the rebirth of her late husband.

An old man tells them that there used to be a father daughter duo who lived in the haveli 50 years ago, the daughter, Ragini was very beautiful and many boys were smitten by her beauty but her father never let any guy near her, at the age of 20, Ragini died due to snake bite but her soul still resides in the haveli in search of a man who'll do masti with her.
