As the world's leading expert in the field of horse whispering, Amelia (Anna Emerson) has been invited to speak at the Texas Equine conference. Lucy (Lizzie Bates) is delighted - the trip gives her a good chance of bagging herself a genuine American cowboy - and Jane (Catriona Knox) has decided that, while in Dallas, she'll use the time to get to the bottom of the JFK conspiracy once and for all.

However, an encounter on the flight over with drunken American military man General Dick Munro (Gordon Kennedy) changes their plans dramatically.

Instead of listening to Amelia talk about talking to horses, the team will be chasing aliens across the Arizona desert. So begins a strange odyssey into the twilight zone in which our team of plucky truth seekers are assailed by carjackers, horses, extremely powerful chillies and one of the most annoying Satnav's ever created. Will they make it across the desert one piece? Will there be any aliens waiting for them if they do?

Find out in this final white knuckle adventure of the series.
