There's a Letter from Halime (Halime'den Mektup Var) (translated)

Halime'den Mektup Var (There's a Letter from Halime) is a 1964 black-and-white Turkish adventure drama written and directed by Süha Doğan, produced by Ali Ünal for Ünal Film, with cinematography by Şevket Kıymaz.

The story opens at the end of the Turkish War of Independence, as five demobilized comrades-in-arms promise that whoever falls on hard times will be able to count on the others. Many years later one of them, terrorized by three thugs who extort the town and harass his daughters, sends word to his old friends. Now too old to fight themselves, the veterans dispatch their grown sons instead — and the father who has no son sends his daughter Halime, raised like a boy, disguised in men's clothing.

As the four young avengers take on the gang, Halime's true identity comes to light and she falls for the young man from Erzurum; once the farm is rid of the villains, the couples are happily married. Ahmet Mekin (as the man from Erzurum) and Sevda Ferdağ (as Halime) head a cast that also features Yılmaz Güney, Turgut Özatay, Hüseyin Baradan, Necdet Tosun, Kadir Savun and Muharrem Gürses.
