Marie Dressler plays the title character, tugboat captain Annie Brennan, in this 1933 Hollywood box office hit. Her husband Terry (Wallace Beery) is a lazy, bragging drunk. Robert Young plays their son Alec, who has big ambitions and winds up as captain of a fancy ocean liner. The ocean liner's owner is Red Severn (Willard Robertson), whose daughter Pat (Maureen O'Sullivan) is the object of Alec's longings. Young tries to get his mother to leave his father and join him on the ocean liner, but she refuses out of love for her husband and her tugboat.
