Mrs. Manson (Alma Hall Irma P. Hall) spends time with her cat, who is kind and wise, but becomes a stumbling block to a casino vault robbery. The mastermind of the robbery is the notorious Professor Higginson (Tom Hanks Tom Hanks). He fooled Mrs. Manson by claiming that he had acted like a poet at the University of Mississippi. Under Higginson's leadership, a large group of people from all walks of life moved into Mrs. Manson's rented apartment, where they pretended to rehearse church songs, essentially opening an underground tunnel to the vault. Of course, the avatar invited to cope with such an arduous task. There are generals who have dug tunnels, props on the set, black people who run errands in casinos, and even a former American football player. Everyone is working hard and is on the verge of success, but they never thought that Mrs. Manson would become their nightmare.
