“Psych 2: Lassie Come Home” will premiere on Wednesday, July 15 — aka Peacock’s national launch day. In the sequel, “Santa Barbara Police Chief Carlton Lassiter (Timothy Omundson) is ambushed on the job and left for dead.” Then, in a “vintage ‘Psych’-style Hitchcockian nod, he begins to see impossible happenings around his recovery clinic.” (Watch a teaser trailer here.)

Among the service’s other launch-day offerings:

• “Brave New World,” a series adaptation of the classic sci-fi novel, starring Alden Ehrenreich (“Solo: A Star Wars Story”) as John the Savage.
• “The Capture,” a UK conspiracy thriller exploring pressing questions about surveillance and misinformation following the arrest of a former soldier (played by Callum Turner of “Fantastic Beasts”).
• “Intelligence,” a workplace comedy set in the UK’s Government Communications Headquarters, starring “Friends” vet David Schwimmer.
• Sports-themed docs “In Deep With Ryan Lochte” (which chronicles the Olympian’s last chance to make Team USA following the 2016 Rio Olympics scandal) and “Lost Speedways” (a docuseries that explores great racing cathedrals of the past, created and hosted by Dale Earnhardt Jr.).
• Children’s programs “Cleopatra in Space,” “Curious George” and “Where’s Waldo?”

Peacock Premium customers can stream all first-season episodes of “Brave New World,” “The Capture,” “Intelligence” and “Lost Speedways” upon launch.

Peacock is already available to Comcast’s Xfinity X1 and Flex customers following a soft launch on April 15. Upon its national debut in July, the NBCUniversal streaming service will offer a free, ad-supported tier, as well as options for ad-free service. Peacock Free and Peacock Premium (the latter of which costs $4.99 a month for non-bundled Comcast and Cox subscribers) both will come with ads, but premium customers can upgrade to an ad-free experience for an additional $5 per month. (Any customer can also purchase the ad-free experience directly for $9.99 per month.)
