Into the Weeds (2022)

Dewayne Johnson, a Bay Area groundskeeper, suffered from rashes in 2014 and wondered if they were caused by the herbicide he'd been using for the past couple years. As his health deteriorated, Johnson became the face of a David-and-Goliath legal battle to hold a multi-national agrochemical corporation accountable for a product with allegedly misleading labelling.

Unfortunately the movie Into the Weeds is not yet available on HBO Max.
