An insidious new drug hits New York. Danny recruits Colleen for the fight, and Claire discovers that credit cards can have many uses.
A new synthetic heroin appears in New York City. Rand connects it to the Hand; but Ward dismisses it. After a chemical factory owned by the Rand Enterprises on Staten Island produces carcinogenic waste chemicals, Rand personally apologizes to a complaining citizen, with the conversation being recorded by a lawyer and later disclosed to the media.
In a board meeting, where Rand is absent, Ward convinces the shareholders to stand against the accusations instead of accepting responsibility. However, the anxiety of being always watched by Harold causes Ward to have a drug overdose.
Rand meets Claire Temple, who trains at the dojo. He convinces Wing to help him infiltrate the pier in order to prove his theory. At the pier, they find the containers apparently loaded with normal supplies. Rand enters one of the containers, where he finds a hidden room housing Radovan, the chemist who created the formula since the Hand has his daughter hostage. Rand engages and overpowers a bodyguard after the latter critically stabs Radovan, whom Rand takes to the dojo, where Temple stabilizes him. Wing vows to help Rand defeat the Hand, which is revealed to be run by Wilson Fisk's old ally Madame Gao.
