Cairo, 1980. Musa, a brilliant Egyptian professor, cannot move past the grief of losing his only son, Yusuf, an officer who died fighting the Israelis in 1956. Musa has been developing a method to travel through time in order to save his son from death. He succeeds and wakes up during the war – but unexpectedly finds himself in the body of an Israeli soldier named Ben. It’s as if Musa has woken up in a nightmare. While Musa looks for his son, Ben takes over Musa’s life in 1980s Cairo. Musa increasingly loses his grip on his own identity. Should he stay in the present and reclaim his life, or return to 1956 to complete his mission?
