It is the last day on the job for hospital volunteer Sharon (Nancy Hoffman). When the volunteers assemble at the start of the day, head volunteer Sarge (Sharon Thorpe) notices that Sharon is absent. Sarge finds Sharon performing oral sex with a doctor and takes her back to work. As the volunteers go about their duties, they have various sexual encounters with the patients and staff.
At the end of the day, staff and patients hold a party for the departing Sharon. Sarge walks in. When Sharon confronts Sarge and calls her a “prude,” Sarge reacts by pulling up her dress and forcing Sharon to pleasure her. The party promptly becomes a sex orgy.
