When Elliot's engagement ring doesn't fit, Keith agrees to a "redo" in which Elliot plans her own engagement. Carla, Jordan and Elliot's sorority sister Melody gather to help plan the "surprise." Meanwhile, the men of Sacred Heart are suffering from too much talk and not enough action: J.D. keeps trying to take it past "macking" with Melody, but she keeps shooting him down, Turk and Carla have not been intimate since their baby was born, and Dr. Kelso's internet is down -- resulting in a lot of cold showers. With Elliot's engagement, her colleagues all fantasize about being married to her, each with their own personal twist.
