End of spy drama Alias

'Alias' star Jennifer Garner.

Alias is going undercover for good.

The spy drama starring Jennifer Garner will end its five-season run in May 2006. "Alias is not going to wind down as it comes to an end, it's going to rev up, and we're going to make it the event it deserves to be," the network said.

The show has been struggling to hold its audience.
