Grace gets a visit from her critical, over-the-top mother, a would-be star whose propensity for breaking out into show tunes and impersonations dismays her daughter -- and delights Will, Jack and Karen. She also wreaks havoc by suggesting Will and Grace wed, despite their sexual differences. When Will winces at the fantasy of committing to anyone who needs to be the star of a relationship, it's an eye-opener for Grace, who sees she's more of a chip off the old block than she imagined. Meanwhile, Karen thinks she might be pregnant so Jack helps her take a pregnancy test.
The show takes place in New York City and focuses on Will Truman, a gay man and lawyer, and his best friend Grace Adler, a Jewish woman who runs her own interior design firm.
Also featured are their friends Karen Walker, a rich socialite, and Jack McFarland, a struggling actor/singer/dancer who also has had brief careers as an acting teacher, back-up dancer, cater-waiter, talk-show host and student nurse.
