Temple Sky Showcase, 9pm

Mark Strong (above) returns for the second series of the drama about a surgeon who sets up his own illicit clinic under a tube station – and he’s joined by Daniel Mays, Carice van Houten and new recruit Rhys Ifans. In the opening episode Milton wants to forget about the bunker and concentrate on his family, but that’s going to be difficult, especially as his wife Beth wants answers. Meanwhile, Lee faces a crisis.
