A dead wolf, released from its sanctuary by Jonjo, is found at his father's abattoir, increasing animosity between Lauren, who orders its closure, and Frank, whilst Annie learns that unpleasant doctor Simon Marr, who sacked Niall for being gay, owns to running the wolf over and asking for its incineration at the abattoir.
