On campus, Indah is known as an impromptu mechanic who can use improvised tools to repair cars. This skill is not liked by Angga, a new student and chairman of the Tiger Claw Club. Angga also sabotages Indah's work by ordering Rendi to harm himself using the car that Indah repairs.

Geri is amazed by Indah's ability to repair her car. He also offered Indah to work as a mechanic in Wijaya's workshop. Indah is willing and officially becomes a mechanic in his workshop. However, when Indah began to feel comfortable working, Indra caught her and asked her to be honest and tell Ramlan, her father.

Angga is surprised by the fact that Indah is the main reason why Wijaya's workshop is busy. Angga is increasingly curious and interested in Indah's abilities. As time goes by, their relationship gets closer and makes Alexa jealous. Alexa asked Marko to harm Indah.

Indah finally knows the secret of Ramlan's past as a racer, has the heart to choose racing over accompanying Sari, her mother gives birth, even when Sari dies Ramlan doesn't accompany her. Indah was very disappointed and left Ramlan. At a time like this only Geri was willing to come and comfort Indah.

Indra asked Indah to forgive Ramlan, who had raised her and had to live with guilt. Indah gave in and forgave Ramlan. Meanwhile, Sakti starts running an illegal drug smuggling business at Wijaya's workshop.

Ramlan asked Indah to stop working as a mechanic and cut ties with Geri. Indah was disappointed but couldn't do anything. On the other hand, the authorities have arrested Wijaya for drug smuggling. All activities at the garage were stopped, all cars were also confiscated.

Indah, Geri and Angga try to investigate Sakti's illegal business. Angga also asked Alexa and Dika to supervise Sakti's activities. They almost got information about Sakti's rottenness from Bang Dom, unfortunately they were thwarted by Sakti's men. Bang Dom was run over and died.

Sakti's drug transaction place was finally revealed by Dika. Indah, Geri and Angga immediately came up with a plan and went to the place to catch Sakti. There was a chase and scuffle, but in the end Sakti was caught.

The police searched and confiscated Sakti's house and assets. Wijaya was released, his workshop can be opened and operating again. Meanwhile Indah is still pursuing Ramlan's blessing to be allowed to be Geri's mechanic in the upcoming drag race.

Indah was devastated by the accident that befell her father. Indah felt guilty if it had not been selfish to get into the automotive world, Ramlan would not have come to the training ground and had an accident. He doesn't even want to be Geri's mechanic anymore and cancels attending the national drag race.
