A man discovers a photo from 1982 that confirms his brother-in-law was not where he said he was when his wife (the man's sister-in-law) was murdered, prompting the man to call people in an attempt to solve a 35-year-old murder mystery.

The Landline Detective

6B is the anthology feature film of five Hawaii filmmakers. Each of the four stories revolve around rooms with the number 6B and the film examines the darker side of island life: a man struggling with drug addiction has a revelation about his identity; an ex-con must enter an underground poker game to reunite with his daughter; a young woman befriends her neighbor, a former hit man; and a local family deals with an impending tsunami. 6B features an all-Hawaii cast, crew, and production.
