While GUTS is looking into a mass sighting of an angel, Captain Iruma visits her estranged son, Tomoki, who now lives with her late husband's mother. Iruma's mother-in-law has seen the angel too and, like many others, believes it is a sign of Judgement Day. However, GUTS finds strong evidence that a familiar and malevolent force has returned to try destroy Ultraman Tiga. (Source: TV Tropes)
