PREVIOUS: Fresh off the heels of “Parenthood’s” finale, Erika Christensen has been cast in ABC’s drama pilot “L.A. Crime,” Variety has learned.

The period drama from ABC Studios explores sex, politics and pop culture across different eras in Los Angeles history, with the first season set in the “rock ‘n’ roll, coke-infused revelry of the 1980s,” following a pair of LAPD cops searching for serial killers on the Sunset Strip.

Christensen will play Betty, a nurse and mother of two who naively falls hard for a man by the name of Kent, while out on the strip. Enamored by him, yet frightened and enlightened by his strange kinks, the two form a connection and begin a dangerous partnership.

Subsequent seasons of “L.A. Crime” will cover a different era and storyline. Variety has learned Christensen has signed on as a one-year regular.

Steven Baigelman penned the pilot and will exec produce with Mandeville Television’s David Hoberman, Todd Lieberman and Laurie Zaks. Tom Shankland is set to direct.

Christensen is repped by the Gersh Agency.
