Blood Money - S4.E3

Not even motherhood has clamed young Al Dangerfield. She still thinks she knows best but, as usual, ends up regretting it. When she sees a young Serbian, Dejan, beaten on the street of Warwick, Al steps in to help him. A passionate relationship begins and Al refuses to accept any criticism of her new-found friend, least of all from her father. But there's much more to Dejan than meets the eye, as Al's forced to realise.

Out of compassion, Dangerfield's daughter Al takes into her home Dejan, a young man who has been brutally beaten up. But Dangerfield becomes suspicious and asks DS Diamond to check him out.
