Sweet Death follows Dr Philip Nitschke, euthanasia’s top advocate, as he loses his medical license and decides to become a stand up comedian, presenting a show that teaches euthanasia in countries where it is illegal. In parallel to this, we follow Kathy, who after attending one of Dr Nitschke's workshops travels to the Northern Mexican city of Tijuana to buy on the black market the means to kill herself should she inherit her mother's debilitating illness.
