Julian Sklar (Ian McKellen) was once a star of London’s 1960’s and 70’s pop art explosion, but he hasn’t painted in decades and has been broke for years. His two estranged children (Jessica Gunning, James Corden), desperate for an inheritance, hire Lori (Michaela Coel), an art restorer and former forger, to pose as a prospective assistant in order to access 8 unfinished canvases Julian has buried deep in storage. Her plan is to complete them, then return them to storage, where they are to be “discovered” upon Julian’s death.
