Variety game show.

A casual encounter between Adriana and Sergio, two former high school friends, triggers the beginning of the game of the keys where four couples generate new sexual and emotional combinations in a dangerous and lustful game.

The game consists of everyone putting their keys in a bowl. At random, each one chooses some keys and he must go to spend the night with the owner of the keys. This game will revolutionize the group of friends and their lives. It will make them discover who they are and what they really want.

In a characteristically cinematic documentary series shot on both land and sea, Sir David Attenborough narrates the struggles and successes of a wide variety of animals as they take on one of life's most vital challenges: finding a partner. From termites to humpback whales, each creature's particular quirks and rituals are explored with joyful fascination as they navigate the dramatic - and sometimes dangerous - path of love, ensuring the survival of their species by relying on their animal instincts. With the production team having recorded over 4000 hours of fights, rebuffed advances and incredible displays aimed to impress, the veteran natural historian once again shows the animal kingdom as it has never quite been seen before.
