Rehab touches upon one of the most controversial aspects of the Lebanese civil war: the right wing militias whose actions resulted in large numbers of violent deaths. Sleepless Nights explores the story of Assaad Shaftari, an officer responsible for such manoeuvres during the war. The film probes the unexplained disappearances of fighters who went missing at the hands of these militia and focuses on Maryam Saiidi who is looking to uncover the truth about her missing son. The encounter between Assaad and Maryam, when it comes, is both explosive and poignant.
