When tattoo artist, ex-con, and patched member of Sin City MC's Oakland Chapter Gavin "Saint" Lawson meets Oya Williams a professor and an older woman fourteen years his senior, he's immediately attracted to her. He makes it his mission to convince Oya that age is just a number. He'll do whatever it takes to keep her a part of his life, including protecting her from her very powerful ex-husband who can't take no for an answer.

The Sinners never leave until all the cards are played.
