It is just another day in the small town of Hamlin until something disastrous happens. Suddenly, news breaks that a series of nuclear warheads has been dropped along the Eastern Seaboard and, more locally, in California. As people begin coping with the devastating aftermath of the attacks — many suffer radiation poisoning — the Wetherly family tries to survive.
Unfortunately the movie Testament is not yet available on HBO Max.
