The film kicks off at an airport where Marjane Satrapi finds herself unable to board her flight back to Iran. As she sits to smoke a cigarette, she reflects on her childhood memories from 1978 when she was just nine years old. Back then, Marji fantasized about becoming a prophet and emulating Bruce Lee. Simultaneously, her innocent dreams unfold against the backdrop of a fierce uprising against the US-supported Shah of Iran, with her middle-class family actively participating in protests, fueled by aspirations for a better society.
Throughout this tumultuous period, Marji struggles to connect with her peers’ perspectives, whether it involves confronting the child of a despised government official or vying for the prestige of having a family member who has been a political prisoner the longest. In a moment of youthful rebellion, Marji and her friends plot to confront a boy whose father is known for executing Communists without remorse, but just in time, her mother intervenes. That night, God manifests to Marji, imparting lessons on forgiveness and cautioning her against seeking justice through her own actions.
One significant evening, Uncle Anoush, newly released from prison, visits for dinner and shares tales of his evasion from government forces due to his Communist beliefs. His experiences serve as a subtle warning for Marji about the consequences of standing against oppression. As political strife ends and new elections take place, hope quickly fades when Islamic Fundamentalists assume control, enforcing a repressive regime that further crushes Iranian society. Laws become increasingly harsh, enforcing modest dress for women— including the mandatory hijab— and leading to Anoush's re-arrest and execution due to his political views.
Disheartened, Marji turns away from her ambitions of prophecy as she and her family adapt to the realities of a regime that is intolerant and oppressive. The outbreak of the Iran-Iraq war brings devastating realities, forcing Marji to confront the brutalities of death and destruction. She witnesses her father being menaced by armed teenage officials and experiences the agonizing loss of her uncle, denied essential medical care due to a corrupt government system. As a way to cope, the family seeks solace in secretive gatherings to enjoy simple joys, like alcohol, that the government has outlawed.
As she matures, Marji’s defiance grows; she secretly acquires Western heavy metal albums from the black market, dons non-conformist outfits like denim jackets, and unflinchingly challenges a teacher's fabrications about government abuses. Fearing for her safety due to her outspoken nature, her parents send her to a boarding school in Vienna, Austria, in 1983 for better prospects. However, upon her arrival, Marji finds herself on edge with the judgmental nuns and feels deeply alienated in a foreign environment, surrounded by people who take their freedoms for granted and make her self-conscious about her Iranian identity.
Her feelings of shame intensify when a passionate romance with a charming local man ends tragically on her eighteenth birthday when she catches him unfaithful. Following a series of unfortunate events, Marji finds herself without a home, nearly succumbing to bronchitis before being rescued. Eventually regaining her health, she returns to Iran in 1993, hoping for an improved life as the war concludes. Regrettably, she soon becomes engulfed in despair over Iran's deteriorating state and her family's plight.
In a poignant dream, both God and Karl Marx’s spirit appear to her, reminding her of her values and motivating her to embrace life once more. Revitalized, she enrolls in university, attends parties, and kindles a romantic relationship with a fellow student. Yet, alongside her renewed spirit, realities of systemic oppression become more apparent; heinous acts against political dissidents and absurdities of religious laws plague daily life. Determined, Marji challenges gender biases and voices her frustrations against the system, including confrontation with police officers who reprimand her for simply running to class.
To navigate the harsh reality, she employs survival strategies, like falsely accusing a man of harassment to evade being arrested for wearing makeup, or hastily marrying her boyfriend to escape scrutiny by the religious police. A staunch reminder from her grandmother about her grandfather's and uncle's sacrifices for freedom instills within Marji the significance of not abandoning her beliefs or family, even amidst oppression.
However, her marriage crumbles, culminating in a tragic incident where a police raid during a party leads to a friend's death while attempting to escape. Following these harrowing events and her subsequent divorce, her family decides that to ensure her safety from government persecution, Marji must leave Iran once more—this time for good. She acquiesces, and shortly after, her grandmother passes away.
In the present day, Marji is once again unable to re-enter Iran. As she takes a taxi from the airport, the driver inquires about her origins. With a heavy sigh, she responds, "Iran." Her final reminiscence is of her grandmother, who used to tell her how she would tuck jasmine into her brassiere, allowing her to carry a lovely scent every day.
