British actress Kate Robertson is living the dream: she's got a successful acting career, a mansion in Beverly Hills, great friends, and a hunky boyfriend. Once she gets her dream role in the remake of the science fiction classic Memories, Kate gets very excited. However, since she and director Ken Lyons are both connected to a Los Angeles criminal gang known as los Diablos, her self-centered co-star John Farrell becomes a full-fledged member of a rival gang known as the Sharks. Once they discover that the two remaining gangs in the city - the Volgograd Bratva and the Hong Kong Triad - merge with each other with the goal of ruling the Los Angeles criminal underworld for themselves, the cast and crew of Memories must put their differences aside in order to avoid being exterminated in the Battle for Los Angeles.
