Three women and four men: Everyone has a mobile phone, which makes a total of seven mobile phones. When the friends come together for dinner one evening, they suddenly come up with an idea. They play a game: Everyone puts their cell phone in the middle of the table and no matter who gets which pictures or messages sent, no matter how brief - everything has to be shared with the others. Telephone calls are only allowed via the loudspeaker. But what starts as an entertaining pastime, which should bring a little tension in the evening, soon leads to some embarrassing and tense situations full of surprises. And soon, not only the mood threatens to tilt, the long-standing relationships are at stake through the discovery of explosive lies and secrets at stake.
