An ingratiating bride develops warm ties to her father-in-law while her cold husband blithely slights her for another woman.
Yapool, an ancient interdimensional race of beings tries to conquer the Planet Earth with his army of monsters, called Terrible-Monsters. The newest member of the Ultra Brothers, Ultraman Ace, arrives on Earth to aid humanity in the battle against Yapool. Touched by the sacrifices of Seiji Hokuto and Yuko Minami, he revives them and grants them the Ultra Rings, which allows them to transform into Ultraman Ace in times of need.
In a fight between two giant monsters named Takkong and Zazahn, young race car driver Hideki Go is killed while trying to rescue a little boy and a dog from the falling rubble. His valiant sacrifice is noted by everyone, even his friends and the new defense force MAT, but an unseen being also takes notice. Looking over Go is the "New Ultraman", who is so touched by Go's actions that he decides to combine his life force with that of Hideki, thus bringing him back to life. Hideki Go then joins the MAT and fights alongside them and Ultraman against monsters and alien invaders.
