Rob Stewart died in a tragic diving accident in early 2017 while filming in the Florida Keys, but the tragedy did not stop his team from continuing his legacy through the upcoming film Sharkwater: Extinction. An official trailer was released Wednesday, with a target release date set for Oct. 5.

The film will focus on the destructive global shark-fin trade, which devastates the population of sharks worldwide. The trailer shows Stewart traveling around the globe, with several scenes in Costa Rica, trying to hold government officials accountable and filming sharks in their natural habitat. Stewart's accident is mentioned in the trailer, and it will be interesting to see how the cast — which includes Brock Cahill, Madison Stewart, Will Allen and Regina Domingo — will be able to complete the film in the aftermath. This is a follow-up to the 2006 film Sharkwater, which was written and directed by Stewart.
