Adam, een jonge Nieuw-Zeelandse Samoaanse man onderneemt een reis naar zijn moederland Samoa om indruk te maken op Mary, waar hij stapelverliefd op is. Er is echter één probleem: Mary beweert dat ze alleen van "echte eilanders" houdt.

Adam is a 22 year old New Zealand born Samoan guy who falls for Mary. On a 'chance' encounter he learns that Mary only wants to go out with a 'real island guy' - not a plastic one. Adam realizes that to get rid of his 'plastic' ways and impress Mary, he'll have to travel to Samoa and have his cousins teach him how to be a real island guy. Three Wise Cousins is a feature length comedy, that will have you laughing from start to end; it's a film unlike any other that will surprise you with it's endless amount of 'wisdom'.
