Hard Sun (BBC One, 9.35pm)

A DRAMA series about detectives who stumble across a government conspiracy while investigating a death may not sound particularly original – but the secret that cops Charlie Hicks (Jim Sturgess) and Elaine Renko (Agyness Deyn) uncover in Hard Sun involves the end of the world. The mismatched officers are dealing with a murder in the inner-city when they find proof that the Earth faces certain destruction in just five years due to a mysterious cosmic event, a fact the powers-that-be would very much like to keep under wraps. The duo must use every bit of their ingenuity to protect themselves as they are pursued by Secret Service operatives who are willing to silence them for good. And how can they keep their loved ones safe and uphold the law in a world that is running out of time?

Hugh’s Wild West (BBC Two, 6.15pm)

He begins in the Wye Valley and the Forest of Dean – internationally important protected landscapes straddling the border between England and Wales. There, he catches minnows in the River Wye, gets an insight into the life of Britain’s only aquatic songbird, and meets an IT technician who has set up miniature cameras in his garden to record animals.
