Mummy’s Boys

Phillip Browning is convinced the mysterious deaths are the result of a mummy's curse, and vows to break the pattern by returning King Pharatime's treasures to their tomb. He organizes an Egyptian expedition and recruits crew who will help him keep his plan hidden if necessary. This belief drives the mission from the outset, setting the stage for danger and intrigue.

Stanley Wright and Aloysius Whittaker answer Browning's newspaper advertisement to join the expedition. Whittaker presents himself as an Egyptian expert, while Wright's spells of forgetfulness force him to nap to cure them. Despite these quirks, Browning hires them for the mission.

On the ship to Egypt, the group meets Sterling, who is part of the expedition. Catfish, a stowaway claiming to be from Cairo, is invited to join the group. Wright and Whittaker later discover that Catfish is from Cairo, Illinois, adding another layer of comic confusion.

After they arrive at their hotel, Sterling disappears and a threatening note is found. The note hints at danger and raises suspicion among the group. This marks the first trace of trouble in the expedition.

At the encampment, Whittaker, Wright and Mary wake to find Catfish tied up and everyone else gone. A second threatening note is found in Browning's tent. They read Browning's instructions directing them to dig toward the tomb entrance and move the treasure boxes inside.

The three men dig until the tomb entrance is cleared and begin carrying the treasure boxes into the tomb. The scene cuts to a secret tomb room where Sterling has Browning tied and gagged. Sterling reveals his plan to murder the others with an undetectable poison syringe.

A landslide seals the tomb entrance, trapping Whittaker, Wright, Mary and Catfish inside. They search for a way out while Sterling continues his deception. The danger deepens as they realize escape will be difficult.

Sterling approaches them, pretending to be a kidnapping victim and professing belief in the curse. Wright reveals that the deaths were murders and that he has read a diary, though he cannot recall where he hid it. He says he needs a nap to remember, creating a tense moment of memory lapse.

Sterling offers to inject him with a sedative, triggering a chase through the tomb. Wright hits Sterling on the head with a vase, shattering it and revealing the diary. Whittaker reads the diary and confirms Sterling as the killer.

The police arrive at the camp, enter the tomb, and take Sterling into custody. Rasheed Bey, the Egyptian secret policeman, had warned Wright by phone and was investigating Sterling. The revelation confirms Sterling as the murderer.

With Sterling captured, the truth comes to light and order is restored. Wright has something he wants to say to Mary but cannot remember what it is. The ending leaves a hint of unresolved romance due to the memory lapse.

The diary's discovery ties the murders to Sterling and confirms the investigation's outcome. The expedition closes with a sense of relief and a tease of romance, underscoring the lighter tone despite the danger endured. The Egyptian authorities continue to monitor the aftermath as the travelers head home.
