If it seems too good to be true, it probably is. A maxim that five couples, from Canada and the UK, should have taken to heart before accepting the invitation for a free return holiday to Cuba, from cousins - Alberto and Miguel Mistro.Because there is a catch: the hosts need the guests to bring back the flea market purchases from their last trip and help them decipher the clues on the items to break a six-hundred-year-old conundrum. But it’s a race against time, as the couples battle with shadowy gun toting figures, personality clashes, disappearing guests, injuries and their own personal demons. But they have no choice but to unlock the secrets of the Mistro family, and solve the Cuban Conundrum, if they are to survive.
