What story would be totally different with cellphones or birth control?S

We live in an age of wonders. Modern innovations have transformed our world, notably including instantaneous global communication and birth control. Which story do you find yourself watching or reading, and thinking: "if only they could text each other, or use condoms, this would go way differently"?

Please include a picture or clip of this story that would go totally different with better communication or contraception. And mention the name and how things would go differently. Thanks!
