The hosts are ex-burglars who have the skills and knowledge of burgling to help instruct people on ways to improve their security and protection. It's always interesting to watch how they rob a family or person of their entire possessions and do it so quickly that their getaway is almost perfect.
After the owners return and realize they have been robbed, they return their possessions as well as giving them much needed protection for their safety and to help prevent further burglaries and break-ins.
The show is always interesting to watch and keeps me entertained since they always steal so much in so little time. It a show that keeps us informed about the dangers of robbers and also shows us the chaos of burglaries and theft in action.
