When Tanya eventually rescues herself from a drug dealing lifestyle in Western Sydney’s lowly Cabramatta, she finds reprieve in society by becoming a hot-shot lawyer. Together, with her merchant banker husband Mark, they seemed headed for the very top of Sydney’s elite.

That is until she is confronted with the catastrophic effect the warming climate will have on Sydney and indeed the rest of humanity.

To her surprise, she finds a committed ally in her father-in-law David. They persuade an often reluctant family to develop an enclave, called The Settlement, in the Blue Mountains west of Sydney in preparation for what’s about to take place.

When disaster strikes, will they survive?
