Furlong (2019)

Abbey tags along with her brother Jack and his best friend Sam at a beautiful spot in the California mountains. Called Furlong, it's where teens go to jump off cliffs into a pool of water below. As they bike to the spot together, Abbey has a fascination with her brother's best friend, who also seems to see her in a new light. But when a flirtatious gambit goes wrong, an initially innocent outing takes a darker, murkier turn.
