Undercover as an Intern, I Caught His Mistress and Went Nuclear

As part of a deal with her husband, Shane Ford, a wife goes undercover as an intern at his company for a week. On her first day, a woman storms the lobby waving a certified marriage certificate, declaring herself the one and only Mrs. Ford and ordering staff about. A coworker warns that the woman is Shane's first love and that crossing her is dangerous.

Unshaken, the wife calls her brother and tells him to bring Shane down with divorce papers, wanting him on his knees within five minutes. The woman, Wendy Jasper, humiliates her over coffee, pours scalding coffee on her hand, and threatens her job, while supervisors grovel and warn that Wendy is untouchable. Yet the wife knows her own marriage certificate is locked in a safe at home, and she resolves to see how far Wendy will go with Shane's protection.

When Wendy tries to pour outside food into the cafeteria's communal soup pot, the manager blocks her. She calls Shane on video, and his gentle voice tells her not to get upset and to put the manager on.
