After saying goodbye to the late Charlie Harper, Alan meets Walden Schmidt (Ashton Kutcher), a broken-hearted billionaire.

Walden's former business partner shows up, looking to patch the rift between them.

Sam introduces Jess to his female best friend; Nick worries Gavin will hurt Schmidt; Winston is troubled by a reaction to a gift.

Chaos reigns in the city when Cooper and Lucero are kidnapped and held hostage by a pair of "tweakers" and our cops join the frantic search to find them... before it is too late.

Jane and Maura track a serial rapist they suspect could be a sailor, but it's Fleet Week in Boston so this is little help in narrowing the field.

In 1958, Maura's femininity causes a family conflict; in 1966, Shelly and Mort have a clandestine affair.
