The Ghostbusters of East Finchley(1995)

The Ghostbusters of East Finchley is a British comedy series following a young man living on a council estate who grows suspicious of his mother's employer. Convinced something illicit is happening, he teams up with a friend and an Inland Revenue investigator to launch a covert tax fraud investigation. The trio adopts the cheeky nickname "Ghostbusters" for their undercover operation, blending amateur sleuthing with bureaucratic procedure as they attempt to expose financial wrongdoing. The series balances comedy with the earnest determination of ordinary people taking on white-collar crime, set against the backdrop of working-class London life.
