Johnny is the `white sheep' of a mafia family, and a terrible embarrassment to them. Just released from jail, after serving time for a crime he didn't commit, he's framed for a murder.
Not wishing to return to prison, he becomes a fugitive. In the first episode, he takes up with a kindly old man in a motorhome. The old man dies (peacefully, while fishing -- no foul play), and Johnny takes off in the motorhome, with his parole officer (who also happens to be his very spiteful ex-wife) in pursuit.
The last name, `Bago', by the way, is an alias he assumed. When the old man asked him his name, he saw the letters B-A-G-O, and not being any more imaginative than that, gave that as his last name. He was looking, at the time, at a partly-covered nameplate identifying the well-known manufacturer of the motorhome -- `Winnebago'.
In subsequent episodes, Johnny meets Elvis Presley, hangs out with a group of environmentalist crackpots, spends time among a group of migrant farm workers who think they see The Virgin Mary in a pattern of mud splattered on the motorhome's windshield, and has a variety of other highly improbable adventures.
