Zvi Luria's idyllic life as a respected engineer and family man begins to crumble when he faces the onset of dementia. Clinging to his identity, Zvi joins an unconventional project with a younger engineer, Asael, to forge a secret military road within the Negev Desert's Ramon Crater. As Zvi grapples with his declining mental faculties, the project confronts an unexpected ethical dilemma: a Palestinian family lives in the path of the planned road, guarded by a mysterious preservationist. Zvi, with his unique blend of professional expertise and newfound vulnerability, proposes a compassionate solution: a tunnel that would preserve the family's home. All the while, his wife Dina, a pediatrician, becomes ill, escalating the stakes of Zvi's personal and moral challenges. 'The Tunnel' weaves together the intimate struggles of marriage, the complexities of identity, and the contentious landscape of Israeli-Palestinian relations into a poignant narrative, peppered with humor and insight.
