Muggs' rich Uncle Pete is coming to visit. Unfortunately, Muggs' late father had bragged that he had seven kids, so Muggs recruits the members of the gang to pose as his family. Things turn sour, however, when a local mobster finds out about Muggs' deception and threatens to expose it.
Unfortunately the movie Clancy Street Boys is not yet available on HBO Max.
