Reid, Jackson and Susan - on the run from the police - and in the care of Jackson's former flame Mimi Morton - must find a way to bring down Assistant Commissioner Dove, and reveal the truth about his long-lost brother, serial hugger Nathaniel. Reid and Jackson discover that Nathaniel was responsible for an attack in which a fight dog was stolen from its owner, and set about finding out the location of the next dogfight. Before they arrive, Nathaniel goes about setting all of the fight dogs free, causing a stampede through Whitechapel. Reid and Jackson pursue, but lose Nathaniel in the crowd. Meanwhile, H division are introduced to their new leader – the feared Inspector Jedidiah Shine, former leader of K division. When Shine learns of Jackson and Reid's attendance at the dogfight, he sets up another in the hope of luring them out to secure their capture.
Reid and Jackson are forced to run for cover when Shine and Thatcher arrive at the theatre, suspecting it to be their hiding place. Jackson is forced to control his trigger finger when Shine threatens to harm Mimi, but she manages to keep her cool. They decide to use the recently deceased body of a docksman as a ploy to smoke Nathaniel out of hiding. They recreate the injuries caused to his earlier victims using wolves' teeth, and leave the body in an alley just yards from Leman Street. Shine, however, is too clever by half and identifies the body as a hoax. When the morning paper portrays Reid as somewhat of a vigilante hero, Shine confronts editor Castello, but his interrogation proves too much for Thatcher - who, fed up with being under the reign of a bully and potential sexual predator, seeks out Reid, Jackson and Susan to offer them much needed help.
Nathaniel, outcast by his brother to a derelict cottage in the countryside outside Whitechapel, finds solace in a fish seller, Mr. Sumner, who visits daily to collect Eels to sell on his fish stall. When Mr. Sumner suddenly dies from a long-suffered illness, Nathaniel offers to help his daughter, Prudence, and her young son, Robin. However, he finds that her brother, Caleb, is less than welcoming. When a thief tries to steal Prudence's takings from the stall, Nathaniel responds by breaking his fingers. Forced to flee, he is later forgiven by Prudence for his actions, but she is later warned of his unhappy tendencies by Augustus. Nathaniel manages to win back her trust, but in the process discovers she is being beaten by Caleb. When he confronts Caleb, the situation turns unhappy, and Nathaniel is forced to watch on as his animal tendencies rise to the surface once more.
Thatcher finds young Robin cowering in fear after the passing of his mother and uncle at the hands of Nathaniel. He passes the boy into the care of Reid, Jackson and Susan, and they manage to uncover information which they believe could lead them to Nathaniel. When they arrive at the Sumner's house, they find it has been meticulously cleaned and the two bodies disposed of. Shine is not far behind, however, but is surprised to learn of the true identity of the hugger. With Reid's information, he confronts Dove and discovers that the rumour of his brother's animal tendencies is true. Dove, however, persuades Shine that Reid is the bigger threat. Reid and Jackson find Robin's body in the river. Jackson decides to end his involvement in Reid's operation, and instead rescue his son from the claws of Dove. Reid, meanwhile, is the victim of a trap set by Shine.
With Reid incarcerated, Jackson and Susan plan their escape with Connor. Susan, however, cannot bare to see Mathilda's relationship with her father lay in ruins, and in an attack of conscience, hatches a plan with Jackson to break Reid out of custody. Reid, however, has other ideas and refuses to go along with Jackson's plan. Having sent Thatcher to exhume the body of Robin Sumner in the hope of proving Dove's guilt, Reid lies in wait for the walls of H division to come crashing around him. Dove, however, is warned of Thatcher's plans and at the boy's graveside, executes Thatcher's demise and disposes his body in the river. Nathaniel, however, is witness the entire event and takes Robin's body to Susan. Meanwhile, Castello decides to contact an old friend of H division - Chief Inspector Abberline - to help her prove Dove's involvement in the cuddles.
