Okay, here are a few options for a "Tomorrow War" plot description in English, depending on which specific movie (there are a couple with this title or similar themes) you're referring to. The most prominent one recently is the Tom Holland film.
Assuming you mean the Tom Holland movie "Tomorrow War" (2022):
Plot Description:
In the near future, humanity faces an existential threat from "The Invaders," a technologically superior alien species determined to conquer Earth. To combat this overwhelming force, the U.S. government has secretly developed the "Global Defense Initiative" (GDI), a program that enables soldiers to be sent back in time to 1985.
The protagonist, an unnamed U.S. Army soldier (portrayed by Tom Holland), is selected for this dangerous mission. His specific task is to travel to 1985 Los Angeles and assassinate Albert Einstein. The GDI believes that by eliminating the theoretical physicist who developed the atomic bomb, the Cold War might never have happened, thereby preventing the nuclear advancements that The Invaders have exploited to become so powerful.
Despite the immense personal cost and the questionable morality of his assignment, the soldier is sent back. He arrives in 1985, grappling with the paradox of changing history and the task of assassinating a man he believes to be a historical icon. He must navigate the vibrant, pre-internet era while avoiding detection and carrying out his orders, all while realizing the potentially devastating consequences if he fails or if the timeline changes in unexpected ways.
The plot follows his attempts to find and eliminate Einstein, his interactions with historical figures and ordinary people in 1985, and the escalating threat as The Invaders' presence begins to subtly (and sometimes overtly) disrupt the past, potentially altering his future.
In short: A future soldier is sent back to 1985 on a secret mission to assassinate Albert Einstein to prevent an alien invasion, forcing him to confront history, morality, and the unpredictable nature of time travel.
If you were thinking of a different "Tomorrow War" (e.g., the anime OVA):
The original "Tomorrow War" (明日戦争 Ashita Senso) is a 1989 Japanese OVA (Original Video Animation) by Studio Deen.
Plot Description for the OVA:
In the year 2016, humanity is engaged in a devastating war against the alien species known as the "Invaders" (BETA). The Earth is in ruins, and humanity's only hope lies in the massive superweapon, the "Super Dimension Fortress Macross," which is piloted by the elite team known as the "SDF Macross Force."
The story primarily follows the character of Isamu Yashima, a young man who becomes involved with the SDF Macross Force. He pilots a variable fighter and fights alongside his friends and fellow pilots against the relentless BETA. The OVA focuses on the intense aerial battles, the camaraderie among the pilots, and their struggle for survival against overwhelming odds.
The BETA are a highly advanced, insectoid-like alien race with a massive fleet that has decimated human colonies across the galaxy. The Macross Force, using advanced technology and the strategic advantages of the Macross aircraft (which can transform into a giant robot), becomes humanity's last line of defense.
The plot centers on the desperate battles, the human cost of war, and the determination of the Macross Force to protect Earth, even as the odds seem dire. It explores themes of war, loss, friendship, and the will to fight for survival.
In short: A young pilot joins humanity's elite SDF Macross Force as they fight a desperate war against a powerful alien invasion in 2016, focusing on the aerial battles, the pilots' struggles, and their fight for Earth's survival.
