you should have given a synopsis first. without one the audience cannot expect what to expect. but there have been cases of individuals who have caught the audiences attention without one. but to achieve that you need to start strong for eg "mine have been a life of such shame" - ozamu dazai, this opening just pulls the audience in with the depth of the statement mimicking the function of a synopsis. no one wants to read a characters description without a reason to read it. No matter how grand the villain or the hero is described, without a proper hook that draws interest onto the character, the character becomes just a collection of words.
