Rubi Malone (Eliza Dushku) is a "problem-solver": a bounty hunter and general mercenary. In the game's prologue, she is hired to retrieve a briefcase that is hijacked by a gang. She does so, leaving numerous dead gang members in her wake, and delivers the case to a hospital. It turns out to contain a human heart, which a powerful man named William Ackers (William Morgan Sheppard) needs to survive. Rubi delivers the case to Ackers's grateful son, collects her fee, and departs.
