The Tomlinson family is composed of five children: the eldest, Liam (Payne), is a teacher in Spain; Louis (Tomlinson), who is a successful career woman in New York; Eleanor (Calder), the middle child who is a London-based, independent film assistant director; Gabbie (Tomlinson), who is also a teacher and lives at home with their mother; and Niall (Horan), the youngest and bright son. Niall shocks his brother and sisters by announcing his intent to marry Demetria lovato (Lovato), his girlfriend of four months. The eldest and the girls are not pleased. After years of being estranged, the only older brother and the three remaining sisters band together to dissuade their brother Niall from marrying his fiancée. As they try to put their plan into action, the Tomlinson siblings also confront emotions and issues they have long suppressed.
