Getting along with some colleagues can be rough, but working with your mom? That's a whole other story. When Katie, an up-and-coming news producer, finds out her overbearing mom has rejoined the workforce as an intern at Katie's TV station, it might just be the worst news ever. But, with her biggest cheerleader at her side, Katie might finally get the recognition she deserves!
Chuck is having cataract surgery and, for the first time ever, must miss a day of work. Carol, eager to shirk her overwhelming intern duties, offers to take care of him. Meanwhile, Katie is excited for a peaceful day but with Chuck gone, Greg is reluctant to be the bad guy. As a result, "The Breakdown" descends into chaos as Greg is forced to say yes to Portia, Justin and everyone else's "great ideas for the show."
Katie's secret war reporter boyfriend, Trip, is back in town and working at the MMN offices. Despite Katie's best efforts, Carol quickly uncovers the covert relationship using a plan she stole from "Days of Our Lives". Meanwhile, Chuck, feeling threatened by Trip, is determined to return to the field. Greg and Justin support the idea until they find footage of Chuck's time as a war reporter in the '90s.
After organizing a poorly attended staff karaoke night, Carol is convinced that everyone at "The Breakdown" needs some office bonding time. When Greg refuses to help, Carol enlists the help of God, causing a huge snowstorm to trap everyone in the building overnight. Chuck takes an interest in working with Katie, which Portia convinces Katie is romantic. Carol saves the day when she breaks into the offices of competitor "Morning Wined Up with Kelly and Mary Kelly" and steals all the morning show's wine.
When a field reporter at "The Breakdown" is exposed as an arsonist, Katie gets an opportunity to appear on the air. Carol, embracing the role of stage mom, becomes obsessed with propelling Katie to fame. Katie must choose between her personal ambitions and making her mother happy. Meanwhile, Chuck, jealous of Portia's many creative pursuits, tries to compose a new theme song for the show.
Carol is excited when Chuck asks her to wait for the cable guy at his townhouse, until Chuck gives an ominous warning that tests her curiosity. Meanwhile, Portia's phone gets hacked and Katie struggles not to read her private emails.
Katie secretly investigates a celebrity phone hacking ring behind Greg's back. In Katie's absence, Carol falls into producing a piece on her favorite phone game, "Biscuit Blitz." Meanwhile, Chuck gets in hot water when Portia accuses him of mansplaining.
Carol has a midterm she must pass in order to keep her internship. Katie needs to choose between helping her mom and focusing on her hacking story, which she can't seem to crack. Meanwhile, Greg's wealthy estranged grandmother (guest star Christina Pickles) pays a visit to the office. Chuck finds her cold and cruel, but almost immediately falls in love with her.
Katie makes a huge discovery about the story she's been chasing and, with the help of Carol and the rest of the staff, concocts a scheme to get the story out. Greg struggles with balancing his conflicting loyalties to his family, co-workers and conscience.
