Fantasy & sci-fi · Seedance 2.0 · Alexandra Aisling · 2026-10-16

A short-line story prompt for a 15-second sci-fi short: each line is one beat, going from a race to the star, through a dogfight in plasma, to silence and a final reveal inside the star.

Prompt

Try it on Seedance 2.0

15-second cinematic photorealistic science-fiction action short, 16:9. Two enormous space fleets race toward a dying red giant. The first fleet is trying to reach the star. The second fleet is trying to destroy them before they arrive. Hundreds of fighters collide in combat while both fleets plunge directly into the star's outer atmosphere. Ships weave between colossal solar eruptions. Missiles vanish inside rivers of plasma. A small spacecraft breaks away from the battle and dives toward the star's surface. An enemy fighter follows. The two ships disappear beneath the glowing surface. Suddenly everything becomes silent. The camera reveals an enormous geometric structure hidden inside the star. Its surface begins opening. A blinding beam erupts outward. The star isn't dying. Something inside it has just awakened. Photorealistic stellar physics, extreme scale, aggressive space combat, fast pursuit, plasma environments, dramatic reveal, cinematic camera movement, detailed spacecraft, no text, no logos, no anime, no cartoon.

Make it yours

At 15 seconds the story has about ten beats; keep the dogfight to one line and give the structure reveal at least 4 seconds by deleting the missiles-in-plasma line.
The prompt already carries 'no text, no logos, no anime, no cartoon'; keep it, since sci-fi scenes often get stray HUD text.
To get a clearer ending, replace 'The star isn't dying' with a visual: 'beam erupts from the opening, camera pulls back'.
