Nixon and Hunter investigate when a pensioner is found sealed in the freezer of his own basement. Initial suspicion falls on the elderly man's cleaner, who appears to have been accepting a more than generous wage as well as a number of gifts from her employer. However, Nixon is convinced that the man's son isn't telling the whole truth and soon comes to realise that he may have been trying to frame the cleaner to throw the scent from himself. Meanwhile, Perkins' day goes from bad to worse when he ends up receiving a beating whilst trying to protect Max Little, before investigating a dodgy translator representing a Togoan national who has been accused of theft by her employers.
