When Greg's former co-worker and ex-girlfriend Barbara is transferred back to his firm from Washington, Dharma seeks to assuage her own natural jealousy by finding a new Mr. Right for Barbara—a quest which takes on a desperate edge when Barbara confesses she is still in love with Greg.

The pretense that everything is fine with Greg's parents finally proves too much for Dharma, who snaps during dinner at a Chinese restaurant and has the bad news served to Greg in a fortune cookie (to the absorbed interest of the Chinese family sharing their table). Trying to help the Montgomery's non-existent sex life, Dharma takes Kitty to her local neighborhood erotica store, where they naturally run into Abby and Larry. Greg and Pete take Edward for a drink to commiserate, and Edward demonstrates his ace in pick-up lines: ""Excuse me, young lady, do you have change for a million?"" Meanwhile, Jane has gone off to a Star Trek convention (""I like middle-aged men who are virgins""), leaving her pet Mr. Boots with Dharma and Greg; but Greg freaks out when he discovers that Mr. Boots is not exactly a cat.

After catching Dharma innocently hanging out with her old college tutor---and failed suitor---Charlie, an enraged Greg moves out. Then the misunderstanding turns into a crisis as they both get caught up in the planning of their mutual friends' impending wedding, compelling Greg to seriously reevaluate his own crazy marriage. But when he finally sees the light, it may be too late.
