If you are a guide dog, then being picky at work does not suit you. So the Labrador Trison entered the service of a very unusual ward. You can’t run or play with a blind old lady, but he did his job perfectly, no matter what. True, everything soon changed, fate brought a surprise. And the faithful assistant ended up with completely different owners. The guide became... a security guard! It seemed that being on guard in a kindergarten was easy, until a terrible event happened there. However, Trison is not an ordinary dog, so even in a critical situation he was able to show his best side!
