Karl and Wendy are mourning the loss of their son Alex, who passed when he was just an infant. Karl seeks the help of Dr. Francis, a psychologist who prescribes several unconventional methods for coping with the loss, from Bonsai therapy to speaking to representative love objects. Wendy, enabled by their live-in nanny, a mysterious Latina girl, indulges in a delusion that begins to push Karl to the edge, and herself further away from accepting the loss. A dark comedy in the realm of Sam Shepard and Martin McDonagh, All the Dead Biddles explores how far over the edge that loss can push us.
