After the death of his father Murat II, Mehmet II ascends to the Ottoman throne. After braving internal and external enemies, he decides to complete what he was destined to do: Conquer Constantinople.

Late 19th century in Alexandria. Two traditionally rival Turkish families, "Seferoglu"s and "Tellioglu"s are competing for the "Green Valley". The winner will be determined by Daver Bey, who has a beautiful young daughter, Leyla. Both families try to arrange a marriage between a man from their family and Leyla, so that Daver Bey will be inclined to give the green valley to his "relatives". Tellioglus, who are behind in the race, desperately find a final solution: They will fake their idiotic butler, Saban, as the highest ranked Ottoman soldier in Egypt: Tosun Pasha.

Saban, Ramazan and Bayram are sailors in an Ottoman Navy and Hüsamettin is their commander. Hüsamettin's aide Ramazan, Saban who is foster son of Hüsamettin's sister and Bayram who is married to Hüsamettin's niece stays at Hüsamettin's family residence. Hüsamettin's sister thinks Ramazan is her foster son Saban when she realizes her mistake she introduces Ramazan to her brother as her son in law Bayram since she was afraid of Hüsamettin's short-tempered character. Things get complicated when real Saban and Bayram come to the residence. Now Saban has to be Ramazan and Bayram has to be Saban. Meanwhile, a gulyabani (a ghoul from Turkish folklore) haunts the residence.
