Savage River (2022) is an Australian crime drama set in country Victoria.

There are 3 teenagers who joyride in an abandoned vehicle and find blood in the boot of the car.

One of these 3 is in foster care with a local lawyer running for mayor and her partner, the local pharmacist.

Apart from that 1 event, the child in foster care doesn't commit any crimes, unlike a 'respectable' and protected member of the community.
