The special effects team on this hit action drama gets to strut its stuff in a major way in one of this season’s most anticipated episodes, as a giant tsunami hits the Santa Monica Pier, a major tourist spot, in the new episode "Sink or Swim." Buck and Christopher (Oliver Stark, Gavin McHugh) are among those whose lives are endangered. Ronda Rousey and William Russ guest star; Angela Bassett and Peter Krause also star.
