Lucía and Pablo are Colombian immigrants who've built their lives together in the US yet maintain conflicting attitudes towards their homeland and the extent to which it defines their identity. After undergoing fertility treatment, Pablo finds himself excluded from raising their twins, and the new family situation seems to question the very nature of their relationship and of who they believed they were. In search of respite and time to reflect, Lucía takes the kids to her parents' apartment in Miami. Meanwhile, Pablo learns he is suffering from a syndrome known as 'Holiday Heart'. But is this just a break, or is it really the final days of their marriage?
