The Department is a play inspired by Harold Pinter's The Hothouse. The director of the department, Roote is stressed to the point that he is losing his sanity. His subordinate Gibbs is so ambitious that he undercuts his authority; subordinate Lush is an alcoholic; and his mistress, Miss Cutts, is scheming and having an affair with Gibbs. One of the patients at the house is supposedly murdered, and another is raped and impregnated, so Roote assigns Gibbs to investigate the matter. However, all evidence point to Roote as the perpetrator and Gibbs takes over, leading to further mayhem.
