Louise Young is a devoted single mother whose only priority is to work hard so that she can provide for her daughter, Mia. She has a good job as a PA in a huge international corporation and she's grateful for it. The only problem is her boss who can't seem to keep his hands to himself, but Louise can handle him. What she really doesn't have time for is romance - until she meets the company's rising star, Josh Wallace. Louise has always said no to nights out, preferring to stay in with her child but for one night only, she's decided to let her hair down. It's the office Christmas party, she has a pretty dress to wear and she's looking forward to some champagne and fun with Josh. She's completely unaware that others around her are too busy playing dangerous games to enjoy the party - until she's pulled into those games herself.
