Plot synopsis: Bert and Sam have been living in Spain for the last few years, Sam in the rolling hills and Bert in the slightly less idyllic setting of a prison cell. After a decade behind bars, a cancer diagnosis allows Bert to walk free on compassionate discharge. With only a few weeks to live, she resolves to take on a multi-million-pound art heist that will test her mettle, and prove her worth. Sam reluctantly lets Bert back into her life, and quickly finds herself returning to the life of crime she's tried to leave behind.
