The Ultraman television series and movies have been a staple of Japanese TV since the 1960s. The Ultraman X movie is based upon the Ultraman X series; in fact, I recommend watching the Ultraman X Series Episode 8 - Ultraman X Recap - Encounters and Friends as the movie assumes we know who everyone is and how they relate to each other. I watched the movie first and hand to assume some of the elements. Ultraman grew out of the Godzilla movies and in the first series, many of the costumes used were monsters from the movies. The plot follows the Xio organization as they fight a series of monsters.
Reality TV host Carlos Kurozaki takes an item from an underground pyramid during a show. The gem was the key to keep the monster, Zaigorg, locked away. Zaigorg wants to gain the gem and uses kaiju to Try to gain its powers. Ultraman X, Ultraman Tiga, and the Original Ultraman from 1966 win the day.
