Season three of SUPERMAN & LOIS opens weeks after Superman's defeat of Ally Allston. Clark (Tyler Hoechlin) and Lois (Elizabeth Tulloch) are now working at the Smallville Gazette together and enjoying small town life. But the Kents' romantic bliss only shines a light on how isolating "the secret" can be, as Chrissy (Sofia Hasmik) struggles to balance a new love interest and her friendship with Lois. However, Lois' own work-life balance is put to the test when an undercover assignment reveals a deadly foe that promises to change the Kent family forever. Meanwhile, the Kent boys find themselves being pulled in opposite directions as Jordan (Alex Garfin) discovers what a superhero-identity really means and Jonathan (Michael Bishop) searches for purpose beyond the football field. At the same time, John Henry (Wolé Parks) is haunted by his doppelgänger's past, leading to dangerous consequences for him and Natalie (Tayler Buck).
