They kill both Yavuz and Sevgi while throwing Yiğit from the cliff. Davut finds Yiğit injured, and he brings him to his cabin. After the healing process is done, he gave Yiğit a new identity, Altay Kurtoğlu, and tells him to forget about all, and he hands him to an orphanage. After many years have passed... Altay moves on with his life as a cage fighter. Davut got old and retreated at his cabin, but still he is on top of Altay. One night, the owner of the fight club Doğan, and his girlfriend Esra comes to watch Altay's match. Esra finds an excuse and leaves Doğan for a moment. She goes to the basement to release her friend who is enslaved. Her friend informs Esra that the men they chase are working for 'Goliath (Golyat)' and their goal is to avoid 'Project Lightning (Yıldırım Projesi)'. He sacrifices himself to enable Esra's escape. It is well understood that Esra works as an agent for her country, and her relationship with Doğan is fake. Understanding that Doğan has relations with Goliath, Esra is on the move to secure her daughter Ela. Doğan's men chase after Esra. While Esra tries to escape, she has had an accident while Altay was passing by with his motorcycle, and he helps Esra. Doğan heard that Esra escaped and he chases right after her while sending his guys to Ela's school. Yet, Ela manages to escape the men to go to the meeting point where she and her mother agreed on meeting if anything alarming happens.

Nizam asks the guy near Doğan to kill Esra. In the meantime, Altay sneaks in to the farm to save Esra. While the duo was escaping, the guy shots Esra. Altay takes her again to Davut's cabin. Yet, Esra dies in the arms of Altay, in her last breath she repetitively says 'Goliath and the Project Lightning'. Davut, hearing those words, faces the fact that the organization Goliath, he spent years to end, is still active. Goliath is a dangerous and sneaky organization that is supported by the outside forces to take over the government, and they manipulate the masses by using religion to achieve their goal. Davut spent his youth to get rid of them, yet he failed. His patriot team members died each by each on the team he assembled. Actually, Yiğit's (Altay) father Yavuz was taught by Davut, and he is deceased after he was trying to keep an information given to him.
