'Life After Beth' Clip : "Parks and Recreation" alum Aubrey Plaza and "In Treatment" cast member Dane DeHaan co-star as a teenage couple. DeHaan's character, Zach, is left heartbroken after his girlfriend, Beth, played by Plaza, dies unexpectedly. In the clip that can be viewed below, Zach goes to Beth's house to confront her father, who is played by John C. Reilly. An angry Zach accuses Beth's father of being secretive and trying to keep Beth away from him. Despite Beth's father's attempt to block Zach from going any further into the house, Zach dodges him and rushes to Beth's room -- where he finds a very much alive Beth trying to resist being shoved into a closet by her mother, played by Molly Shannon.
