Dave is making a video that will vault him to global success, but he's forced to face reality as the project threatens to implode.
In the second episode, back from his travels, Dave continues to hold his own feet to the creative fire, but the world has conspired to throw every possible distraction at him- including the prospect of seeing Ally again for the first time since they broke up.
Dave returns Sunday 10th October at 9:45pm on BBC Two.
