The father and son duo are back on the road in their trusty RV, exploring a new part of the world and once again seeking out plenty of thrill-seeking adventures.
Breaking Dad sees son Barney Walsh push his dad - The Chase presenter and The Larkins star Bradley Walsh - out of his comfort zone in an attempt to tick off a series of bucket-list challenges on their sight-seeing travels together.
Over the previous three series, the pair have journeyed to Switzerland, Florida and LA, but in this latest fourth instalment Bradley, 61 and Barney Walsh, 24, embark on a 3,000-mile journey through Europe.
