In a luxury lodge on Botswana's sun-soaked plains, four friends reunite for a birthday celebration... The birthday girl. Has it all, but chose love over her friends... The teacher. Feels the walls of her flat and classroom closing in... The mother. Loves her baby, but desperately needs a break... The introvert. Yearns for adventure after suffering for too long. Arriving at the safari lodge, a feeling of unease settles over them. There's no sign of the party that was promised. There's no phone signal. They're alone, in the wild.
