Plot is a cross between The War of the Worlds (1953), and Invasion of the Body Snatchers (1956). We send a probe to mars, it colects samples and tells about its samples, then it bursts into flames for no reason. The robot transmitted for 6 minutes. The scientist takes couple days off with his family after the failure and appears to live in some sort of palace. The family starts having some illusions and scares around the house and people go to visit them. but NOTHING REALLY HAPPENS.
Eventually doctor meets himself and its actually alien using his body, a martian. he explains a bit about it. He tells them he will be "humane" when things come to end. They decide to destroy it. It is supposed to be made of energy, so they want to change the flow. The alien retaliates and attacks. It kills the whole family and floods the place to clean the remains.
