Instant Family has a whole lot of heart. Director Sean Anders crafts a touching story about the difficulties and profound happiness adopting children. The film uses comedy to highlight the issues of the foster care system. Most prospective parents are looking for infants. They don't want the burden of raising "troubled" older children, especially teens. Instant Family is a testament to the people who care for abandoned children. It takes true compassion and love to embark on this journey.

Pete (Mark Wahlberg) and Ellie (Rose Byrne) are a successful couple in suburban California. Their business flipping houses has finally taken hold. They are able to enjoy the fruits of their labor. Ellie argues with her competitive sister (Allyn Rachel) about having children. She was so busy working, the thought of a baby seemed ridiculous. Ellie goes online to research fostering children. She is deeply moved.

They decide to get certified as foster parents.
