Plot
Don and Ellie Griffin were a New England couple married for twenty years before they divorced. They have three children from their marriage – Lyla, Jared, and adopted son Alejandro, who originates from Colombia.

In preparation for Alejandro's wedding, Ellie arrives at Don's (and her old) home, and lets herself in. She interrupts Don just as he is about to perform oral sex on Bebe, his girlfriend of eight years (and Ellie's former best friend). All are embarrassed, but they make small talk, and he shows Ellie to her room. Meanwhile, Alejandro and his fiancée Missy are meeting with Father Moinighan, the priest who will be marrying them. It is revealed that Alejandro's biological mother Madonna is going to be coming from Colombia to the wedding, which upsets Alejandro since he does not have a "traditional" family, and his Catholic mother would not approve of that or the fact that Don and Ellie had been divorced.

Lyla, who reveals she is separated, goes to the hospital and sees her 29-year-old brother Jared, an OB, after passing out. They talk and it is revealed that he is a virgin and is waiting for the "right one". Back at home, Alejandro tells Ellie about his mother coming to the wedding. Explaining that since she is a devout Catholic and doesn't believe in divorce, Alejandro asks Ellie and Don to pretend to be married for the next three days. Hearing this, Bebe becomes upset and leaves the house, clearly upset at Don. Alejandro's mother arrives with his biological 20-year-old sister, Nuria. Later, Nuria flirts with Jared, after she brazenly strips naked to skinnydip in the family's lake as he watches.

That evening, the family goes out to dinner with Missy and her parents Muffin and Barry, and Bebe shows up as their waitress, which surprises everyone. Meanwhile, Nuria starts fondling Jared under the table, and Ellie sees Nuria giving Jared a handjob. She takes Nuria to the restroom for a chat, telling her that American women behave differently with men. When they arrive home, Jared tells Nuria he wants to have sex, as she had suggested earlier, but she tells him "No", asking him instead to do romantic things for her such as read her poetry. Don and Ellie, meanwhile, end up having sex after Ellie, still pretending to be Don's wife, sleeps in Don's room.

Ellie and Madonna go for a walk in the woods and talk. Neither understands the other's language, though they think they are communicating on some level. At the same time, Don and Lyla talk privately and Lyla reveals she is pregnant. On the wedding day, before the ceremony, Don tells Bebe he had sex with Ellie. Bebe says she forgives them but then punches him in the face. She also reveals that Ellie cheated on Don with Missy's father before Don cheated on her. Muffin says that she knows about Ellie and Barry, and tells them that she is bisexual, implying that she is interested in a sexual affair with both Bebe and Ellie. Meanwhile, Missy and Alejandro have decided to get married on the family dock to escape the chaos. The family runs after them and, after some of them fall into the lake, the wedding reception is on.

During the reception, Jared goes upstairs to talk to Nuria, who tells him she has decided to no longer follow Ellie's advice (about not being so available sexually), and they sleep together. Back at the reception, Ellie and Bebe have made up. Don surprises Bebe by proposing to her, and they get married on the spot. Lyla's husband Andrew arrives at the wedding and, upon finding out that Lyla is pregnant, reconciles with her. Alejandro's mother realizes she has been lied to about his family and he runs after her as she starts to leave. But she reveals that her own past was not as pure as he thought, that she too had lied to protect him, and she forgives him.

Time passes and it is revealed that Lyla has had a daughter named Jane, as Don attaches a plaque with her name to their family tree.
