Plot? Yeah, it had one. It wasn't perfect, but it'll do.
Acting? Pretty stiff. Olga Kalashnikova definitely tries too hard, and her overacting is painfully cringeworthy for most of the film. Kenneth Matepi has a few stiff moments, but he's mostly believable. Some of his lines, particularly early on in the film, were corny and rather limiting. Overall, I think he'd have been more fluid in his native accent. Some of the minor roles actually seemed to be more believable actors. The young Tobias family was impressively smooth.
The cinematography is reasonably well done, especially for an indie, and shows some nice local scenery. One odd element tho, is that Wallace chose to set the film in summer and make big waves at Waimea Bay a key plot point, when winter is the time for north shore surf. Seems like a basic oversight that nobody bothered to correct, and anyone who knows the islands will probably raise an eyebrow.
