Occupation -Police Officer works along side Sgt Catherine Cawood (Sarah Lancashire). Ann Gallagher (Charlie Murphy) is the daughter of billionaire businessman Nevison Gallagher (George Costigan) and his wife Helen (Jill Baker). She is the target of a kidnap plot by Nevison's disgruntled Accountant, Kevin Weatherill (Steve Pemberton) after Nevison refuses to give him a pay rise in order to send his daughter, Melissa (Sydney Wade), to a better school. Kevin makes a deal with local thug Ashley Cowgill (Joe Armstrong) to kidnap Ann and blackmail Nevison for the ransom money, which will be split between them.
Ashley then instructs two of his male employees to kidnap Ann for a cut of the money. The kidnap is carried out by the recently released from prison, notorious, drug dealing rapist, Tommy Lee Royce (James Norton) and Lewis Whippey (Adam Long) who follow Ann as she drives in her Mini, purposely banging into her, resulting in her getting out to confront them. Whilst talking to Lewis she is hit and grabbed from behind by Tommy, she yells and kicks out as she is bundled into a Transit van by Lewis and Tommy. She is then taken to the basement of one of Ashley's houses.
When Lewis returns to Ashley, he leaves Ann at the mercy of Tommy, who rapes her. Lewis works out what Tommy has done when he returns after he spots Ann's underwear on the floor, he then calls Ashley to check if that was part of the plan telling Ashley that he believes Tommy's had Ann and that he hopes the same isn't expected of him because he's no rapist. Lewis refuses to leave Tommy alone with Ann again. They go to the basement to take a photo of Ann to be sent to her father as proof she's alive, but when Tommy goads Ann by putting his hand between her legs, Lewis steps in to stop him, is viciously beaten by Tommy and left in the basement with Ann. When Tommy returns he orders Lewis to leave, which he does in fear of another beating.
Having received a tip-off of Tommy's whereabouts, Sgt Cawood goes to the house where Ann is being held. Ann tries to get her attention as she knocks at the door, her police car is spied by Tommy from a window and of the assumption the police know Ann is there, Tommy calls Ashley asking why there's a policewoman knocking on the door, Ashley is oblivious and he tells Tommy to get Ann ready to be moved. Lewis is driving Ann to the new location in the van as Tommy drives Ann's car, but things get out of hand when Lewis is stopped by PC Kirsten McAskill (Sophie Rundle) because he is speeding.
Tommy is watching on in the mirrors of the car as PC McAskill is talking to Lewis. She also tells Lewis he has a tail light out and asks him to come and look for himself so he can see how dangerous it is. Ann starts making noise to get the attention of PC McAskill, but Lewis tells her it's his Labrador, when she asks what it's called he says "Tommy". Ann starts screaming through her gag. PC MCAskill realising it's a person then insists Lewis opens the door, to which Lewis still insists it's a dog. Tommy then turns the car around and drives to the back of the van. PC McAskill, clocking the car, asks Lewis if the keys are in the ignition and tells him to wait there whilst she retrieves them. On returning she asks Lewis if he knows the person in the car to which he responds "no", she then hands him the keys instructing him to open the back of the van.
Realising Lewis is a liability about to blow it by opening the van, Tommy reverses the car straight at them, Lewis quickly moves out of the way while PC McAskill is crushed between the van and the car. As she falls to the ground she uses her radio to alert her police colleagues of the danger she's in. Tommy responds by reversing over her as a horrified Lewis looks on. Sgt Cawood and other police respond to the call immediately as Tommy runs over her again. He then gets out the car and tells Lewis to get the van off the road "as if you're arse is on fire". Lewis responds by calling him a "nutter" before leaving while Tommy looks down at PC McAskill, whose bloodied and battered body lies in the road. Tommy returns to the car, callously running over her again as he is turning the car to drive away from the scene to catch up with Lewis in the van. Ashley arrives at the van where Ann has been taken and tells Tommy vehicles have been crushed and to take the van and the car and to dump Ann somewhere. Tommy thinks he means kill her, much to Ashley's horror, but Tommy insists she knows too much thanks to Lewis and he's not going back to prison because of this and insists they ask for more money.
At the same time, Ann, realising that Lewis is not like Tommy tries to reason with him into helping her get away, but he insists he can't. Sgt Cawood breaks into the house where Tommy was seen and finds evidence of a hostage situation, but is oblivious to Ann's kidnap. Instead of disposing of Ann as instructed by Ashley, Tommy moves her to his Mother's cellar where he intends to keep her a sex slave. Sgt Cawood finds Ann captive when she visits Tommy's Mother's house after Tommy turned up to her Grandson Ryan's school and told him he's his father. Tommy returns before Ann can be freed and a vicious fight ensues between Sgt Cawood and Tommy. Although they both manage to escape, Sgt Cawood is badly injured and Tommy flees before the police arrive. As the police treat her attack as attempted murder, in hospital, Ann confides in her that Tommy Lee Royce raped her and asks her to tell Nevison, but not Helen, who is dying of cancer.
Ann eventually recovers and joins the police. She also enters into a relationship with Daniel, whose wife divorced him, and by season 3 is happily married to him.
