Heartbeat: O Guilty Man!

SINOPSIS

Rob lands himself in trouble when he spends the night with Helen, getting Geoff to cover his shift - and matters grow complicated after it's revealed that the doctor's estranged husband made the complaint. When a truck careers into a couple's back garden following a routine MOT test Bernie struggles to remember if he changed the bald tyres, and a snooping journalist soon forces the muddled mechanic to flee.
