Brendan's desire for a drink of water in the night takes him on a plumbing adventure, first replacing a kitchen faucet and then enlisting Simon's help to tackle the house's bad pipes from under the house. After finding Frank reading a medical dictionary at 4 am, Shirley makes him an appointment to see Terence who diagnoses him with an enlarged prostate and arranges for Frank to have further tests. A phone call takes Frank out to the roadside where a bus is stopped. High school student Peter Wilson has died suddenly in his seat at the back of the bus. No obvious cause of death is evident and his friends are not eager to tell Frank what they know. When the test results from Terence's autopsy come back, it becomes clear Peter died as the result of sniffing aerosols. Maggie is getting desperate for accommodations but emphatically turns down Judy's suggestion that she move in with Bob and Cookie - although the prospect of regular poker games piques her interest momentarily. Frank hopes to set up a police sponsored "blue-light disco" for the town's youth. Despite Peter's death, Terence has difficulty receiving support from the authorities in publicising the dangers of solvent abuse. Meanwhile, Peter's friends continue the dangerous activity.
