What's the story of Secret Nine and Grandma's birthday party?

In this episode, Angela's mother's 79th birthday party. Angela cleaned up early in the morning and began to prepare. Angela's daughter Katie is sitting in the living room doing her homework. Angela ran upstairs to do her homework. When Angela picked up the cake from the table, she saw her husband Jim's head sticking out of the table. Jim wanted to surprise his mother and scare his brother-in-law Pat in this way, but Angela refused. Angela's mother, Sister Carlo and Pat are here.

Jim immediately hid under the table. Angela's mother went to the bathroom as soon as she entered the room, but she couldn't flush. Carol said she would help, but when she got in, she hid in the bathroom and drank the wine from her sunscreen bottle. Seeing Angela Pat pretending that she couldn't move the cake on the table, she asked Pat to move the cake to make room. At this time, Angela's mother said that she wanted to take pictures of the food, but she couldn't find the camera, so she asked Pat to take pictures with it. Carol lit the candles on the cake, and Pat took a picture of Angela, Carol and their mother. When they wanted to shoot, Katie came down and decided to shoot with four people. Angela's mother read a card to Katie, but when Angela saw that the candle was about to burn out, she blew it out. At this moment, Pat found that the camera was broken. The result is not a photo.

Seeing that Jim Angela couldn't handle it, he told Angela to hide under the table. He came to ask Pat to take the cake. Jim can't let Pat take the cake after Angela hides. Angela hid under the table and heard Carol tell Jim that she had waited for him for so many years and remembered Jim's promise to him. Just then, Katie and her grandmother came down. Carlo wants to establish a close relationship with Katie. Jim made a hullabaloo about at Carol. Pat stopped them and said that he understood everything. Katie realized that something was wrong.

Just then, Angela's mother cut the cake with a knife, which scared Jim to shout. Who knows Angela came back from the outside, so she sneaked out. It was Angela's mother who wanted to drink water, but Pat played a trick and choked on the spider's ice. When everyone was in a hurry, Pat picked up the phone for help, but was hit by the current. At one time, the scene was very chaotic. This is a man dressed as a fireman. He walked into Angela's house. Under the relieved eyes of everyone, he gave Angela's mother a striptease. It turned out that he was not a fireman at all, but a birthday gift from his brother-in-law Pat to his mother-in-law. Fortunately, Angela's mother got nothing in the end. But Katie and Angela don't know what they talked about upstairs. When they came down, they left their suitcase with Jim.
