When they meet in the house, everyone tries to get a diamond necklace for himself or herself. Meanwhile, one of the gang members turns out to be an undercover detective, and the involvement of a tramp Ben who stays in this empty house complicates ths situtation even more.

When the gang escapes via a cellar, "Nephew" leaves the gun on the table, and Forsythe (John Stuart) takes it.
