Brian Cox and Robin Ince send writer and comedian Lucy Beaumont out on the trail of UFO sightings in the extra-terrestrial hotspot of... Hull! 

Lucy is joined by her Mum GIll Adams who claims to have experienced a number of close encounters of the third kind and they return to Longhill Estate where a UFO was reported in the 1960s. 

Local historian Mike Covell takes Lucy through the documented accounts of the prolific number of UFO sightings in and around the East Yorkshire area. 

Brian Cox and Robin Ince host a close encounter of the first kind with comedian Lucy Beaumont, astronomer Maggie Aderin-Pocock, Prof Tim O’Brien and science presenter Dallas Cambell to ask if UFOs and aliens have visited Earth.
