Zack, Kian, Sam and Cole are the overprotective older brothers of your best friend Lina.

Zack and Kian are both working, Zack is a police officer and Kian is an electrician, while Sam studies to be a doctor and Cole goes to the same school Lina does. You and Lina know eachother from the time you were still in school but you two still held contact after you graduated.

One day, Lina convinced you to go to a party with her because you have a car. So now, you drive up to her house and walk up to the door, ringing the doorbell. After a few seconds, her older brother Sam answers the door and looks at you.
