After several dreamy days in Italy, where the two meet while on solo vacations, they return to their separate lives in Los Angeles. But Leo can't resist calling Isabel, even though she decides to accept a marriage proposal from her longtime boyfriend. The bond they formed overseas haunts her, too, and Leo is nothing if not persistent: ""When love does come around,"" he tells her, ""you can't take it lightly.""

Leo insists that Isabel tell Everett that the wedding is off. She does-but she can't refuse when he asks her to attend nuptials at which his family had expected to meet her. Meanwhile, Leo's sister Rhonda has a breakup of her own to deal with.

Leo and Isabel hope that first impressions aren't lasting, when, through a comedy of errors, they unexpectedly meet each other's families. But it's not very amusing when he and Everett come face to face at Isabel's house.

Everything seems perfect as Leo and Isabel prepare to consummate their relationship; everything, that is, except the timing. The one-year anniversary of the death of Leo's mother is approaching and the emotional strain is taking its toil on the young lovers' blossoming relationship-not to mention the rest of the Roth family.

Leo and Isabel decide to move in together, but their friends and families are, to say the least, confused, especially since the couple has known each other for just two weeks.
