In this dating series that uses modern technology to help people find love, 20 single men and women try to find their perfect mates. A dating algorithm is used to help quantify compatibility, using a process that includes in-depth interviews, questionnaires and compatibility testing. That data is used to identify the 10 ideal pairs among the 20 participants. But the results are kept a secret from the singles, who get to know one another socially and undergo weekly tests to try to pick their ideal mates while living together in Hawaii. If the mates they choose do not match that of the data, they must start their search over. If all 20 singles are able to match up with their predetermined partners within 10 attempts, they share the largest cash prize ever awarded by an MTV show and walk away with a potential partner for life.
