After her father dies, Botswanan Precious Ramotse decides to sell her inheritance - 180 cows - and move to the capital Gaborone and open a detective agency. From a young age her father had trained her to develop her memory skills and she has a keen sense of observation. Business is slow, but Precious soon has a secretary, Grace Makutsi and fits in well with her neighbors. Slowly, clients begin to trickle in: a woman who thinks the man who claims to be her father - he had abandoned the family when she was just a young child - is actually an impostor; a woman who thinks her husband is having an affair - a view Grace enthusiastically generally supports since she thinks all men are liars and cheaters; and a factory owner who thinks an employee claiming compensation for an accident is scamming him. Her interest is also drawn to the case of a missing boy but she she must face a powerful local gangster to get the information she needs.
