The Mighty McGurk

The Mighty McGurk is a 1947 film starring Wallace Beery as a boozing exboxer working as a bouncer in a Bowery saloon.

At Ellis Island, an acquaintance offers to pay Slag to round up 50 new immigrants to work for him. The fiftieth man has a young English boy in tow, Nipper Dean Stockwell, an orphan who has been sent to America to live with his uncle Milbane Aubrey Mather. Slag reluctantly agrees to deliver the boy, who would rather stay with him than go to his uncle. When rival work recruiters start a fight, Nipper either loses or throws away the tag bearing Milbanes address. After searching for the uncle, Slag has no choice but to keep the boy and a stray dog Nipper saved from the dogcatchers.In order to complete his deal with the brewers and build the biggest saloon in the Bowery, Mike needs the building occupied by the Salvation Army. He orders Slag to get the group to leave, one way or another. When Slag refuses, Mike blackmails him into it, stating he has evidence that Slag won his championship by fraud his opponent took a dive. To placate his employee, Mike offers to make Slag a partner in his new saloon for 2000, a sum Slag hopes to get as a reward from Nippers uncle. ........
