Four Sisters and a Wedding

After a few years of not being together as a whole family, Teddie, Bobbie, Alex and Gabbie come together for the wedding and have agreed to dissuade their brother CJ from marrying his fiance.  But as they interact with each other for the wedding, the Salazar siblings also face the feelings and issues they’ve tried to keep for the longest time.
 
Are CJ’s four sisters not yet ready to let him go?  Are they truly trying to fix their brother’s life?  Or do they need to fix their own lives first?
