The Unforgivable (2021) starring Sandra Bullock covers kinship and foster care.
The film is based on the 2009 miniseries, Unforgiven, written by Sally Wainwright. Sandra Bullock plays Ruth Slater who has served time for a violent crime and is now desperately trying to get her life back on track.
She's also trying to locate her sister, Katie, but the child protection system isn't helpful and the foster parents would prefer Katie not be told anything about her past.
The film explores the topic of how some people are willing to give a former prisoner a second chance, but many others arent.
