As Peter, Joe, and brian hang out at The Drunken Clam, they decide to do something to shake up their boring lives. They take Peter up on his suggestion to take up skydiving. Peter is invigorated by their jump and keeps up skydiving despite Lois’ concern, even as his jumps usually result in accidents like falling on Meg at dinner, falling on a ninja that killed a woman, and falling on the castle of the Pig King from Angry Birds with only one pig not ended up killed. An accident at the Eiffel Tower replica in Las Vegas lands Peter in the hospital where he meets Mahmoud, a Muslim. He finds he gets along great with Mahmoud. Back at the Drunken Clam, Peter has Mahmoud stop by to introduce him to Quagmire, Joe, and Brian. They find he has nothing in common with them when he refuses to drink or look at other women. Mahmoud introduces Peter to Islamic culture and he becomes interested in becoming a Muslim. Lois has reservations as Peter starts studying Islam in-depth although she decides to let it pass. Joe and Quagmire also voice their suspicions about Mahmoud as Peter tries to dial up Mahmoud twice only to cause some explosions off-screen. Mahmoud later invites Peter to a Muslim get-together but finds himself unwitting involved with terrorists intent on blowing up the Quahog Bridge.
When Peter drops that he is trying to act inauspicious, the guys begin to suspect that he is involved with terrorists. Peter realizes that he has been duped and wants to drop out but Joe convinces him to go along since he is already on the inside. As they go over the plan, Peter finds out that he will be driving the van. Peter is caught when he reveals he is wearing a microphone when trying to scratch an itch near it. Joe and Quagmire hear as they plan is rushed into action. Peter is held at gunpoint and forced to drive the explosives-laden van to the Quahog Bridge. Peter tries to talk Mahmoud out of his plan, but fails. Joe arrives in time with the police to stop him and destroys the detonator by knocking it out of Mahmoud’s hand. Joe mentions that 30 of the terrorists have been arrested and that the rest of the local Muslims are cast under suspicion. Joe thanks Peter for his involvement as Peter decides to call Horace to get a table ready for his friends and family at the Drunken Clam. As he dials his cell phone, the Quahog Bridge explodes and Peter orders everyone to run away.
