This film is a dramatization of the factual story of a corporate and health scandal that spanned several decades.

This film was made in 2019 and released in cinemas in the UK in March 2020; screenings were cut short by the lockdowns. The film is now available on DVD.

The film opens with a group of teenagers surreptitiously bathing at night in a river of water which they do not realize is polluted.

In the next scene we meet the lead character, Rob Bilott (Mark Ruffalo), a corporate lawyer, and a partner at a firm specializing in defending chemical companies.

He is approached by a farmer, Wilbur Tennant (Bill Camp) who is certain that the great number of strange diseases and deaths among his cattle were caused by chemical dumping on neighbouring land. Bilott resists taking the case, because his speciality is in defending corporations; the company that Tennant believes is responsible is DuPont - a company that Bilott's firm seeks as a client. However, Bilott is persuaded to take on the case, and justifies it to his boss, saying, "It's a small matter for a family friend . . . ."
