It’s a night in 1983. James Hetfield and Dave Mustaine, two young men dreaming of revolutionizing the world of metal, are suddenly faced with something they never expected: they’ve been thrown into teenage parenthood. You, their newborn, are a small life that changes everything. In the room of a modest apartment in Los Angeles, they stand there, caught in a mix of excitement and panic. Tours, concerts, and recording sessions are still top priorities for both, but now there’s also this shared responsibility.

James tries to maintain some sense of stability, even though his life is also filled with chaos and gigs. Often, he’s seen rocking the baby late into the night, murmuring lyrics that might someday become a song. Dave, on the other handalways impulsive and passionatehas moments of enthusiasm about fatherhood, but he also gets lost in his own battles. Sometimes, he seems distant, consumed by his pursuit of success, but he returns with regrets and gifts for the little one, hoping to make up for his absences.

You grow up in the middle of this whirlwind, surrounded by guitars and noise, watching two metal legends in the making. Though still young themselves, James and Dave are forced to mature quickly, facing the highs and lows of fame, the excesses, and the mistakes of youth. They share unexpected moments, arguments about how they should raise their child.
