Here the starting situation:
In the evening there was a big meeting to present the project to the customer (a leisure center with a casino, a night club, etc.).
The customer has asked for major changes that need to be completed for the next day, he will wait and spend the night in a local hotel, but must go home (at the other end of the country) tomorrow.
The boss, the project manager and the architect have to work all night. They see that Angela, the secretary, is not yet left and the boss asks her to stay and help them. Angela understands that she can not refuse...
...But another person remained in office: Miss Dahlene, the staff chief, and she does not like that a little secretary spends the night with the three men and can be appreciated by the boss...
