こんなとき、あなたならどうする？

In hyper-connected Tokyo, an anonymous account called @nasan_0422 posts daily hypotheticals that explode into real-life crises: save the train car or your boss? The city fractures as bystanders livestream choices that claim lives. Aiko, a widowed nurse still mourning her husband’s suicide, becomes the account’s unexpected focus when her son is targeted. Her refusal to engage draws global scrutiny, turning her quiet apartment into a battleground of cameras and threats. As dilemmas escalate from personal to catastrophic—sacrificing a hospital wing for a stranger—Aiko discovers the account knows her darkest secrets and may be her late husband’s digital ghost. Racing against a final tweet that will broadcast her choice to millions, Aiko must decide whether to break the cycle with her own death or condemn the system that devoured her family.

INT. TOKYO METRO CAR - NIGHT

Fluorescent lights flicker over packed commuters. Aiko scrolls her phone, earbuds in. The train lurches. A tweet notification lights her screen: “@nasan_0422: 87 people on this train. One dies if you say nothing. Reply ‘save’ and your son dies instead. 60 seconds.”

Aiko freezes. Around her, passengers glance at their own phones. Murmurs rise. A salaryman shouts, “It’s fake!” The countdown ticks on every screen.

Aiko’s thumb hovers. She looks up, meets the eyes of a young mother across the aisle holding a child the same age as her son. The train screams into the next station. Lights cut to black on the sound of a single scream.

In an era of performative outrage and algorithm-driven outrage cycles, this film crystallizes the terror of being forced to choose in public, reflecting our collective exhaustion with moral tests that arrive faster than we can process them.
