In the most ambitious dating experiment ever attempted, 10 single women were selected and put through an extensive matchmaking process to find 10 single guys who are their perfect match. Now all 20 are living together in Puerto Rico trying to figure out their match and if they do, they'll split the largest cash prize in MTV history - ONE MILLION DOLLARS.  But this season….there’s a twist. An 11th girl will join the house as a double match for one of the guys.  It’s a race to the Truth Booth because for one girl going 10 for 10 means going home without love or money.
