Mutta's life has hit rock bottom. He's been fired, blackballed from his profession and now he's had to move back in with his parents. Meanwhile, his kid brother Hibito has been literally riding a rocket and training to be an astronaut. The same career Mutta once dreamed of. So, is it ever too late to go after your dreams? Through a little coercing and a bit of covert activity, Mutta's family and friends can get his resume on the right desk, but from that point on it will be up to Mutta himself. Does he have what it takes to turn his life around and put his footprint on the moon? The first step on the highway to the stars is always the hardest, and in a job where crash and burn isn't just a euphemism, it will be the biggest risk Mutta's ever taken. But with the best support team ever, maybe he'll find what he needs to rekindle the spark inside him and light the biggest candle of them all!
