They Thought This Was Normal?? THE COLT FAMILY: Australia's Darkest Family Secret

Imagine growing up without school. Your entire world is one house. One family. And when you're born into that world... you don't know anything is wrong. Because to you... this is normal. For decades... an entire family lived hidden from society in Australia. When authorities finally entered their property... they found children who could barely speak. Adults who didn't understand basic hygiene. And a family tree so tangled... investigators struggled to map it. Some called them Australia's most inbred family.
