Nino and Yasmina are born seconds apart in Beirut, unknowingly bound by fate. Their childhoods unfold amid the city's chaos: Nino loses both parents in a tragic accident, while Yasmina's family disintegrates after her parents' divorce. When they finally meet at school, an inexplicable spark ignites. As children, they dream of escaping the city together on a ""magic"" train. But on the night of their planned departure, Yasmina never appears—torn away by her mother—and vanishes from Nino's life. Twenty-five years later, cosmic events reunite them. Nino now runs his family's restaurant, a beacon of warmth and optimism. Yasmina, hardened by life, is preparing to leave Beirut for good. She confesses the truth about that fateful night, and despite herself, is drawn into Nino's joyful world. Against her own resistance, she falls in love and chooses to stay. When Yasmina unexpectedly becomes pregnant, the couple must confront their opposing views on bringing new life into a broken world. Set against Beirut's eternal cycle of destruction and rebirth—and accompanied by a mysterious astronomical phenomenon—their story reveals that stability may not come from avoiding pain, but from embracing the fragile balance between sorrow and joy: the very rhythm of Beirut's defiant heartbeat.
