A three-month-old baby wakes up the size of a skyscraper, and the only person who can calm him is his mom, racing across a collapsing city.

The premise takes one ordinary domestic image and blows it up to impossible scale. A three-month-old baby becomes a skyscraper-sized creature crawling through a modern downtown, and the show treats the destruction completely straight: buildings fall, streets crack open, and the machines of the city are useless against an opponent that cannot be reasoned with by force. The official setup gives the scale of the catastrophe and the military's inability to stop it.
The series runs 20 episodes in English, with the opening stretch playable on the official YourChannel player. That opening stretch stays on the day of the transformation: the baby's rampage, the failed military response, and the mother's crossing of the crumbling downtown. The official page does not provide a more detailed scene-by-scene plot beyond this premise, so later developments are left to the show itself.
The emotional core is not the monster but the mother. Every weapon in the city fails, which leaves one person who speaks the language the baby actually understands: his mom. The opening arc follows her crossing rooftops and collapsing streets with a building-sized bottle, trying to reach the infant before the city is ground apart. The drama is a race between military firepower and maternal reach, and it is the mother who is framed as the real solution.

The Mother, The Giant Baby and The Military carry the opening arc.
Described only as the baby's mom, she is the one person the colossal infant will respond to. While the military engages with firepower, she crosses crumbling rooftops carrying a building-sized bottle, trying to reach him before the city is destroyed.
A three-month-old who grows to skyscraper size overnight and crawls through downtown, crushing everything underfoot. Missiles and the military cannot stop him; he is not malevolent, only enormous, hungry and frightened.
Called in to halt the rampaging infant, the military deploys its weapons and finds them useless against a target that shrugs off missiles. Their failure is what narrows the solution down to the mother alone.
Four editorial picks from the opening stretch — the transformation, the failed counterattack and the mother's race. No ending spoilers.
A three-month-old baby wakes up skyscraper-sized and begins crawling through downtown, turning an ordinary infant into a city-scale catastrophe before anyone can react.
The military is called in and engages, but its weapons fail to slow the giant baby. The show establishes early that force is not an answer to an enormous but not-evil child.
With the city crumbling around her, the mother becomes the only viable solution, moving across collapsing rooftops toward the infant.
She races to reach him with a building-sized bottle, the one gesture that might calm a creature the size of a tower block, before the downtown is reduced to rubble.

Written from the opening arc. These are editorial impressions, not audience scores.
The hook is pure high-concept: take the most helpless creature there is and make it bigger than the buildings. The show commits to the scale, and the comedy-horror of an infant as a natural disaster is what carries the opening.
Because the threat cannot be fought, the drama shifts away from action and onto the mother. It turns a monster-movie setup into a domestic story at an absurd scale, which is the choice that keeps it watchable.
Best for viewers who want a high-concept, scale-driven disaster with a darkly absurd hook rather than a serious military thriller. The appeal is the ridiculous premise played straight: a city unable to stop a giant baby, and a mother who has to be the answer. If you expect grounded warfare or a slow relationship story, this one stays with the rampage and the rooftop race.
