The mysterious red lines overlaying the initial scene and the 'Stranger Things' branding on the walkie-talkie.

The ad opens with two young people, a girl and a boy, in a dimly lit room that looks like a basement or attic. Red lines overlay the scene, suggesting a game or puzzle. The boy holds a walkie-talkie. The scene transitions to a close-up of the walkie-talkie, which has the 'Stranger Things' logo. The lighting shifts to a blue, ethereal glow. The two characters look at each other, then the girl gestures. The scene then shows a close-up of a game manual with instructions and a Morse code alphabet. The boy is shown using the walkie-talkie, which lights up. The manual is shown again with a finger pointing to the Morse code. The characters are seen writing on a notepad. A card with a character and the number '6' is shown. A small figurine of a character is shown floating. The walkie-talkie is shown again, with cards popping out of it. The ad concludes with a display of all the collectible figurines in their cases, followed by the YuMe logo and website.
