Season 4

Casualty (1986), Season 4 — twelve BBC drama episodes from 1989, watch online on iFILM. Holby's emergency department doesn't get twelve episodes by accident: there's more story to tell this year.

Patients still arrive in waves — chain reactions, a flood mid-season, lives upended by forces beyond anyone's control — but the pressure from outside the ward grows harder to ignore. Budget constraints and labour friction start squeezing the unit from all sides. Some staff members hang on. Some take stock of whether they should. Season four is where the show stops pretending the institution itself is fine. Stream Casualty Season 4 all episodes on iFILM.
