Ace hacker, former sex worker and vigilante, Lexi Winter is now a cop and not keen to revisit her criminal past. But when old friends invoke the wrath of a local motorcycle club - the same club Lexi herself used to work for - she races to help them the only way she can: undercover.

If Lexi is to save a child's life, she is going to have to go back - back to a life she thought she had outrun. Back to the person she used to be. But her timing isn't great. Former club president Arthur Cronin has finished his long prison sentence and is out for revenge for the death of his wife and child. As he launches a series of bomb attacks on the club members who set him up and the cops who took him down, Lexi is caught in the middle.

Torn between old loyalties and new responsibilities, she must decide once and for all which side she's on, but even if she does decide to break free, are her old criminal friends ready to let her go?
