Explosive Mission: No Delay - Episode 4

A packed subway car erupts in petty conflict as a child complains about the heat and other passengers scold the family, when an urgent call cuts through: Ms. Langley is told a bomb will detonate in twenty minutes and that only she can save everyone. Callers demand she "send me the micro-imaging data right now" so a disarming plan can be prepared. Voices escalate from explanations to commands; someone insists "Give it to me!" The episode ends with Ms. Langley still en route, the imaging undelivered, and the countdown tightening.
