The film opens with a brief action sequence in which a gangster (Roxy Robinson) is "splurged" by a rival gang of mobsters (Dandy Dan's gang)
using rapid-fire custard-shooting "splurge guns". (Once splurged, a kid is "all washed up" and his career in crime is over?the splurged gangsters are
never shown as dead or even unconscious, merely "finished".)
At Fat Sam's, there is much dancing and singing, but Sam himself is worried about his rival Dandy Dan. He has just found out about the splurged gangster, who was one of his men. Blousey Brown, an aspiring singer, has come for an audition, but Sam is too distracted. Our hero, Bugsy Malone, meets Blousey when he trips over her luggage. He is smitten, and flirts with her, but she plays hard-to-get. Suddenly, Fat Sam's is raided by Dandy Dan's men, who shoot the place up. Sam declares, "This means WAR!" (from wikipedia.org)
