So Jonathan (Hiddleston) gets tapped by Angela (Broadchurch's Olivia Colman) to go undercover and infiltrate Dickie Roper's organization.
That more or less sums it up.
Of course, all of this is way under the radar. Angela is doing it off the books because she can't get clearance from the uppity-ups. She does have some American guy helping her, though.
Then there's a lot of setup, just to get to the point where Jonathan saves Roper's son from would-be extortionist kidnappers. He's badly hurt in the process but begs for "no police," and Roper is, of course, grateful enough to take Jonathan home like a stray and nurse him back to health. Still, there are questions. Roper recognizes Jonathan from the hotel in Switzerland, for one thing. Lots of background checking that spits Jonathan out as a common thief. [To be clear, Jonathan has an assumed name at this point, but I've forgotten it. It's already taking all my energy not to think of him as Chris Pine, or even just Tom Hiddleston.]
The weakest points in the story thus far continue to be Jonathan falling into bed with women—just seems really unbelievable for some reason—and Hugh Laurie as at all threatening. He has his moments, but on the whole I'm not feeling it. Yet. Maybe this is the kind of thing that intensifies as we go along.
I do think the life insurance ads are a funny counterpoint, though.
