The newest episode of "Royal Pains" Season 7 will still follow the adventures of young doctor Hank Lawson (Mark Feuerstein) and his bevy of rich patients in the Hamptons.

In "Secret Asian Man," Hank's brother Evan (Paulo Costanzo) worries that the secret project Boris Kuester von Jurgens-Ratenicz (Campbell Scott) roped him into is way over his head, TV Guide reports. He earlier found out that the wealthy German businessman was keeping a secret laboratory inside the hospital where he was allegedly keeping all the missing equipment.

Meanwhile, Ken Keller (Michael B. Silver) calls Hank for help when he suffers an embarrassing medical problem. The doctor believes, however, that his girlfriend may be affecting his health in more ways than one.

Divya Katdare (Reshma Shetty), Hank's assistant, treats a group of Civil War reenactors who seem to be suffering from a disease more likely to afflict their ancestors. Evan's wife Page (Brooke D'Orsay) is still busy with house repairs, and viewers wonder how long it will take for it to finish.

Promotional photos of the show released earlier also hint that Dr. Jeremiah Sacani (Ben Shenkman) will return soon, according to Cartermatt. In the previous episodes, Boris sent the doctor on a business trip to the center of rare diseases. Jeremiah went missing after failing to show up at the country house.

Last episode, Hank went to Manhattan with Olympia Houston, played by guest star Vanessa Williams. Their time away, however, was not exactly what he expected. Divya had a surprise visitor from her past, which led her to feel confounded by the men in her life. Meanwhile, Paige, was shocked to discover the reason behind the delay in the construction of her house. Contractor Gus was apparently living on the premises and even had a microwave and a TV set up.

"Royal Pains" Season 7 Episode 6 will air  at 10:01 p.m. Tuesday on USA Network.
