Criss (James Marsden) and Liz (Tina Fey) decide to celebrate Valentine's Day, but they need to buy a dining room table first. Jack (Alec Baldwin) entertains his mother-in-law, Diana (Mary Steenburgen), as Jenna (Jane Krakowski) frantically looks to Pete (Scott Adsit) to fill in last-minute as the producer of her first live performance on "America's Kidz Got Singing." Back at the office, Tracy (Tracy Morgan) and Frank (Judah Friedlander) try to help Lutz (John Lutz) find someone to spend Valentine's with.

When Hank Hooper (Ken Howard) threatens to cancel 'TGS', Jack (Alec Baldwin) convinces him to allow Liz and company the chance to do their 100th episode. To produce the best show possible, however, Liz must deal with less-than-ideal working conditions. Amidst the chaos of show preparation, Jack starts doubting a key decision in his life and Jenna (Jane Krakowski) contemplates motherhood.

Liz and Kenneth go into detective mode to track Tracy down. Meanwhile, Jack helps Jenna make sure her new project is financially successful.

Jack puts Liz in charge of an event for Angie in the hopes that she can manipulate Angie into making an appeal to Tracy. Love returns to Frank's life.
