A desperate Hetty takes Geoffrey up and down the streets and sidewalks of town advertising the detective agency. This proves to be a wise method of business, as they pick up a client: a woman whose estranged son, who has been diagnosed with schizophrenia, has disappeared from his sheltered housing unit. As Hetty investigates, she discovers that the woman's son, Reg, has had a hard time being accepted by society, as well as his stepfather, who turns out to have been the person who threw Reg into the streets in the first place. As it becomes clear that Reg has gone off his medicine, Hetty finds herself in a race against the clock to try and find the man before he hurts himself or others in his delusional state. (thetvdb.com)
