The comedian sets about finding his mother-in-law Gill somewhere to retire to - and quickly - before she moves in with him. Armed with his GCSE in Spanish and the cheapest car rental he can find, Jon takes her on a road trip across Spain to find her the perfect place in the sun. The only problem is that Gill wants to grow old disgracefully. Cue a journey that takes in sex, drugs and rock 'n' roll - with some guns and cats thrown in for good measure.
